LM35D Analog Temperature Sensor Module With Cable

The LM35D Analog Temperature Sensor Module measures temperature by outputting an analog voltage (a continuously varying electrical signal) that increases by exactly 10 millivolts for every 1 degree Celsius rise in temperature. The lm35 analog temperature sensor runs on 4V to 30V DC at just 60µA current consumption, which is low enough to power from a single Arduino 5V pin without a dedicated power circuit.

The lm35 sensor module outputs a linear voltage that the ADC (Analog to Digital Converter) inside Arduino reads through the analog input pin. One non-obvious detail — the LM35D is calibrated in Celsius only and cannot read below 0°C in its basic single-supply circuit. Long cables between the sensor and the Arduino pick up electrical interference and distort the analog signal, causing temperature jumps of 1°C to 3°C in electrically noisy environments.

The lm35 analog temperature sensor module connects to Arduino and ESP32 through standard three-wire connections using the attached cable. Weather station builders, and robotics project makers use it. StemVolt provide this module tested for confirmed 10mV per degree output at room temperature.
