In this blog post, I am providing you step by step instructions to build a very simple temperature and relative humidity meter for indoor use. All you need to build this project are an Arduino Uno or compatible board, a DHT11 sensor, and a MAX7219 based 8-digit serial 7-segment LED display. The temperature is displayed […]
iBASE Technology Inc, a leader in the manufacture of industrial motherboards and embedded systems, is proud to announce the highly integrated IBQ800 low-power CPU module powered by an Intel® Atom™ x7-E3950 @2.0GHz or x5-E3930 @1.8GHz processor. Designed to operate at extended temperatures ranging from -40°C to +85°C, the IBQ800 is suitable for use in industrial environments and vertical market segments including automation, gaming,

New co-authored paper demonstrates potential ten-fold energy density increase over existing lithium-ion battery technologies. Scientists from Honda Research Institute have collaborated with researchers at California Institute of Technology(Caltech) and NASA’s Jet Propulsion Laboratory to develop a new battery chemistry that enables the use of materials with higher energy density and a more favorable environmental footprint than current battery technologies. The

A thermistor is a type of negative coefficient resistor whose resistance is dependent on temperature, more so than in standard resistors. The resistance of a NTC Negative Temperature Coefficient thermistor (https://en.wikipedia.org/wiki/Thermistor) decreases as temperature rises. The Steinhart-Hart Thermistor Equation or the Beta Model Equation can be used to correlate the thermistor resistance to temperature to which the sensor is exposed.

A Thermistor is a thermal-resistor. It’s just a simple device that changes it’s resistance based on temperature. If the LRD/Photoresistor is day of of arduino class. The thermistor should be day 1.01. (Can I do that?). If you need precise temperature readings, this is not the part for you. Check out the DS18B20, TMP102, or
