Microchip announced the MCP9600—the world’s first thermocouple-conditioning integrated circuit to combine precision instrumentation, a precision temperature sensor and a precision, high-resolution analog-to-digital converter (ADC), in addition to a math engine preprogrammed with the firmware to support a broad range of standard thermocouple types (K, J, T, N, S, E, B and R). Thermocouples are one of the most ubiquitous temperature-measurement devices, due to their robustness and accuracy in harsh, high-temperature environments, and their ability to measure temperature over an extremely wide range. The MCP9600 simplifies thermocouple designs by integrating a number of discrete devices into one chip, which also lowers board area, cost and power consumption.

Microchip also introduced the EMC1182 Evaluation Board (part # ADM00516) today, to enable development with its new six-member family of temperature sensor ICs called the EMC118X. This board is available now for $ 29.99, from microchipDIRECT and any of Microchip’s authorized worldwide distributors. For more info, visit www.microchip.com/get/7TEL
A few old DS1620 temperature sensors. The middle line shows three two character fields: year, week, and revision. The C2 revision made at the end of 1997 never quite worked right for me; I could only get the half degree (Celsius/Kelvin) resolution output from it. The newer D1's provided much higher resolution using code that supposedly works with all DS1620's. That output is a bit peculiar; the resolution can vary over time. From these two D1's, I usually get between 1/120 to 1/125 degree resolution, which far outstrips their claimed accuracy, and likely their unstated precision.
I made this image from several exposures using the Kipi exposure blending tool, a colored gel, a flash, and a translucent breadboard to make the previous two items more fun.
Microchip's new six-member family of temperature sensor ICs, called the EMC118X, is the world’s first family with 1.8V SMBus and I2C™ communications, which is required for interfacing to the latest generation of smartphone, tablet and PC chipsets. Additionally, this integrated low-voltage I/O support reduces cost and board space because it is accomplished without an external voltage level shifter. These are also the first temp sensors to use an advanced sample-frequency-hopping filter, which enables temperature-monitoring traces of up to 8 inches in noisy environments with accurate readings. The EMC118X family serves a broad range of applications in the mobile, commercial and embedded computing markets, by combining the above features with options for dual, triple and quad temperature monitoring, along with hardwired system-shutdown settings that can’t be overridden by software.

Electrical engineers at the University of California San Diego have developed a temperature sensor that runs on only 113 picowatts of power — 628 times lower power than the state of the art and about 10 billion times smaller than a watt. This near-zero-power temperature sensor could extend the battery life of wearable or implantable devices that monitor body temperature, smart home monitoring systems, Internet of Things devices and environmental monitoring systems.

This is a DS18B20 temperature sensor with another right behind it. It is a digital sensor with 1/16 degree Celsius resolution and maybe half degree accuracy. I was trying out a number of different temperature sensors and have come to the conclusion that not only are they all wrong (which is expected), but that the stated accuracy of the digital ones cannot be correct for all the sensors I have tested at the same time. I need to setup some logging and learn about calibration and the algorithms employed. I suppose a simple linear transform (multiply and add) might be enough, but I haven't tried yet.
