LM35 Analog Temperature Sensor Module

Note: If you are looking for a temperature sensor module which works with 3.3V system and offers reliable analog output, please consider the MCP9700 Linear Temperature Sensor manufactured by Cytron with high quality sensor IC from Microchip.

The LM35 Analog Temperature Sensor Module is a low-cost temperature sensing module that provides easy to use sensor. It comes with analog output. This temperature module uses the LM35 Precision Centigrade Temperature Sensor to detect temperature changes and with the onboard components, you can use it right away by providing power of  5VDC. In short, the low-output impedance, linear output, and precise inherent calibration of the LM35 device make interfacing to readout or control circuitry especially easy.
