Interfacing LM35 temperature sensor with a PIC microcontroller Theory The LM35 series of analog temperature sensors are produced by National Semiconductor Corporation and are rated to operate over a -55 °C to 150 °C temperature range. These sensors do not require any external calibration. The outp...
I will teach you all the essential information you need to know about the LM35 in this article, and I will show you how to use an LM35 sensor with the ESP32. You will get a connection guide, ESP32 code for the LM35 sensor, and I will also answer some frequently asked questions about...

V. CIRCUIT WORKING DESCRIPTION The temperature sensor LM35 is employed to sense the temperature from atmosphere. It produces voltage of 10mV for 10c rise in temperature. The output of the Temperature sensor (analogue signal) is fed to the input of the ADC, which converts the analogue ...
Temperature measurements are taken with the help of an LM35 sensor. Thedatasheetof this sensor describes the calculation formula as follows: every 10mV measured means 1 degrees (Celsius). This is simple enough and the ADC within the microcontroller can be used to measure how many 10mV-s are...
Before we proceed with the tutorial it is important to know how the MLX90614 sensor works. There are many temperature sensors available in the market and we have been using theDHT11 SensorandLM35extensively for many applications where atmospheric humidity or temperature has to be measured. Y...
