This was a test to try to remove the UV/IR glass from infront of the foven sensor using conventional glass cutting techniques...the glass shattered and ruined the sensor...
The Global Humidity Sensor Market size is expected to reach $1.6 billion by 2025, rising at a market growth of 8.2% CAGR during the forecast period.
A humidity sensor or hygrometer can sense, measure, and record the air temperature and moisture present in the atmosphere. Humidity sensors are built of two metal plates and a non-conductive polymer film which is placed between the plates. The non-conductive polymer film absorbs air moisture and changes the current voltage between the two plates. Such voltage adjustments are converted into accurate digital readings. Humidity sensors are categorized into relative humidity sensors and absolute humidity (A.H) sensors. The most common types of units used to measure humidity are parts per million (PPM), dew or frost point (DF/PT), and relative humidity. These sensors are used in a range of applications such as HVAC systems, textiles, food processing, medical, weather stations, and automotive industries.
Humidity sensors can, with high accuracy, sense the levels of moisture in the air in real time. The utilization of these sensors is escalating in moisture-sensitive industries like food & beverages, healthcare, and textiles. This is a critical factor which can contribute towards the exponential growth of the market. Apart from this, government regulations in developed economies like North America and Europe have mandated the deployment of these sensors in industries like printing, food processing, and textile. For instance, the Food Safety and Standards Authority of India (FSSAI) have made the adoption of these sensors mandatory in the food & beverage industry. The reason being, higher levels of moisture can lead to contamination and harm the food quality. Another prominent factor that can stimulate market growth is the high demand for contactless sensors. This demand is associated with the potentially hazardous environments like places exposed to radiations.

In the grayness of winter, the blossom of Camelia's in the tropical green houses, is a pleasent event that I was noticed by the FB group of the Botanical Garden of Lyon, France.
I picked up my Konica-Minolta Dynax 5D (a year-2005 APS-C DSLR, see the details below). I equipped the camera with a Konica-Minolta AF DT Zoom 18-70 mm 1:3.5-5.6 (D) lens that I blocked with a piece of gaffer tape on f=24mm corresponding to the focal length 35mm for a 24x36mm format.
I also used a fix 200 ISO sensor sensitivity. The pictures was in the RAW format (3000x2000 pixels). The lens was equipped with a generic Anti-UV protective 55mm filter and its original Konica-Minolta shade hood LB-1092.
Whenever necessarily in low-light conditions, I used the build-in small flashlight (NG 12 at 100 ISO) to complement the ambient light and to restore vivid colors. The camera was used either in the manual « M » mode or the aperture-priority « A » automated mode.

After the session, the RAW files were transferred to the computer using a USB multi-memory cards reader and processed in the latest version of Adode Lightroom Classic (LrC version 14.1.1) that uses the external module Adobe Camera Raw version 17.0.1 for RAW development. The files were then processed as usual using the regular functions of Lightroom. They are presented either as printed files with frame or the full-size JPEG's.
About the camera :
(Wiki) The Konica Minolta Dynax 5D is a Digital SLR camera announced by Konica Minolta on July 15, 2005. It is also known as Maxxum 5D in the USA and (Alpha) αSweet Digital in Japan. It became available from September 2005 and was bundled with the AF DT Zoom 18-70 mm / f4.5-5.6 (D) lens.
The camera features a 6 megapixel CCD sensor. Image files are created at a maximum resolution of 3008 x 2000 pixels and recorded in JPEG (STD, Fine, EX-fine), RAW and RAW+JPEG formats. It uses CompactFlash for storage. The back has a 115,000 2.5" TFT color display.
Main differences between the 7D and the 5D are:
* Less buttons and dials
* Fibre plastic body, as opposed to a magnesium alloy on the 7D, camera is almost 200 g lighter (970g in workin order with the AF DT Zoom 18-70 mm)
* White balance bracketing
* Newly added colour modes, including black and white
The Konica-Minolta was the last DSLR camera engineering before the cession to Sony of the whole photo camera activities of the company.
The tiny PCB on the right hand end of the cableform contains a reflective optoswitch which detects the end of a leaf spring moved when there is paper in the printer.
The original design used batteries and a manually operated switch to illuminate the LEDs. Occasionally the batteries were too discharged to drive the LED strings well, so the design was changed to run off a 12V mains supply.
In order to not run all the time through the day the above circuit was made to replace the switch.
R6 is a light dependent resistor and its resistance value varies with illumination. In daylight it has a low resistance, and in darkness it is high resistance.
The pot allowed some trimming for when dawn/dusk are detected. Once the daylight gets below a certain level the voltage on the base of Q2 has risen enough to turn the transistor on - which then turns on Q1. Q1 supplies 12V power to the LED board.
To prevent some oscillation of on/off states around dusk and dawn R4 provides a small amount of positive feedback to generate some hysteresis.
Overview
D202X is 2 elements PIR sensor, with small detection angle. Mainly used for toys and other small angle requirement products.
PIR sensor sense the motion object, always used to detet the human. There is a detect rang for the PIR sensor. When a people move in or out of the detect rang, the PIR sensor will be triggered. PIR sensor are low-power, small, easy to used. For this reason it can be used for the alarm system and lighting control. PIR sensor also named passive infrared, Pyroelectric or IR motion sensor.
Features

FAQ
1. What can trigger a PIR sensor?
The first cause of PIR false alarms is low or unstable voltage at the detector. Test to make sure the voltage at each PIR is above 13VDC and stable. The second cause of false alarms is sudden infrared movement / heat changes in view of the detector.
2. Do PIR sensors work in the dark?
Yes, motion sensors work in the dark. The way that a motion sensor detects movement has nothing to do with how light or dark it is in the immediate area. Since infrared energy is present and can be detected regardless of the amount of light in the environment, a PIR motion sensor will work just fine in the dark.

from 47 mpx to 12 mpx ... why?! :)
My philosophy is simple, I use lenses based on the area they can cover... OK, there are compromises, lenses that cover 6x9 and larger formats, but there are not exist cameras with that size of sensors on the market. After trying countless old SLR-type lenses and projection glasses, I got in my hands 16mm film camera lenses that do not cover the FF sensor, APS-C is only slightly larger than MFT, and I really liked the Panasonic menu and ergonomics, so I bought the GX80 for further experiments. While processing RAW files, I noticed that the pictures captured by the 16mpx sensor produce a beautiful "grain" resembling film grain ... so I decided to go deep into the past and buy a few of the first Panasonic Lumix cameras, which started the micro 4/3 story :)
GF1 - I think it was created even before the idea of the GX series appeared ;) because only the GF1 is the first in this series to have as many control buttons as the G1 or GX1 models, because after installing the touch screen, the GF series had a very simplified design and ergonomics.
There is still a question about 12mpx and 16mpx or 47mpx FF ? which sensor is more delicious to me, for someone who has been shooting with film for 12 years before get first digital camera and got used to the analog photographic image ... they are very different to me and I see their application according to the stylistics. I would apply 12mpx to B/W photography, I think it is the most suitable. 16mpx is definitely enough when you want something compact, light, colorful, beautiful grain, x2 crop. 47mpx FF when you need "creamy" beauty, accuracy, variety, precise quality, dynamic range, stability, reliability.
that's My story ;)
this photo was taken with S1R and adapted Mamiya-Sekor FC 48mm f1.9 lens from Mamiya Ruby rangefinder camera.

mano filosofija yra paprasta, naudoju objektyvus pagal tai kokį plotą jie sugeba padengti ... OK, yra kompromisų, objektyvai kurie dengia 6x9 ir didesnius formatus, bet prekyboje fotoaparatų su tokiais sensoriais pokolkas nėra. Išbandžius begalę senujų SLR tipo objektyvų ir projekcinių stiklų man į rankas papuolė 16mm kinokameros objektyvai kurie nedengia FF sensoriaus, APS-C vos vos didesni už MFT, o ir Panasonic meniu ir ergonomika man labai patiko, taigi isigyjau GX80 testi tolimesniems eksperimentams. Apdirbant RAW failus pastebėjau, kad 16mpx sensoriaus užfiksuoti kadrai išgauna gražų "grūdą" primenantį juostos grūdą ... taigi nusprendžiau eiti gilyn į praeitį ir isigyti keleta pirmūjų Panasonic Lumix foto kamerų, nuo kurių prasidėjo micro 4/3 istorija :)
GF1 - manau kad jinai sukurta dar prieš atsirandant GX serijos idėjai ;) nes tik GF1 pirmasis iš šios serijos turi tiek valdymo mygtukų kaip G1 ar GX1 modeliuose, nes idiegus lietimui jautrų ekranėlį, GF serijoje buvo labai supaprastintas dizainas ir ergonomika.
Dar liko klausimas dėl 12mpx ir 16mpx ar 47mpx FF ? kuris sensorius man skanesnis, tam kuris 12 metų pyškino su juosta ir priprato prie analoginio fotografijos vaizdinio ... labai jie man skirtingi ir aš matau jų pritaikymą pagal stilistiką. 12mpx aš pritaikyčiau B/W fotografijai, manau jis labiausiai tinkamas. 16mpx tikrai pakanka kai nori kažko kompaktiško, lengvo, spalvingo, gražaus grūdo, x2 crop. 47mpx FF kai reikia "kreminio" gražumo, tikslumo, įvairovės, preciziškos kokybės, dinaminio diapazono fotografijoje, stabilumo, patikimumo.
tai tokia vat ta mano istorija ;)
