If you are looking for a reliable and easy-to-use temperature sensor, the Electro Hub Temperature Sensor LM35 is a great choice. This sensor is based on the LM35 integrated circuit, which is calibrated directly in Celsius and has a linear output voltage proportional to the temperature. The sensor operates from 4V to 20V and draws only 60 μA of current, making it suitable for battery-powered applications. The sensor has a low self-heating of less than 0.1°C in still air and a low output impedance of 0.1 Ω for 1-mA load. The sensor can measure temperatures from -55°C to 150°C with an accuracy of 10mV per degree Celsius, which means that for every degree change in temperature, the output voltage changes by 10 mV. The sensor comes in a 3-pin package that can be easily interfaced with any microcontroller or display device. The Electro Hub Temperature Sensor LM35 is ideal for power supplies, battery management, HVAC, appliances, and other applications that require accurate and stable temperature measurement.
