NTC Based Temperature Sensor Module h2 sensor These are Metal Film ResistorThis 4 Pin NTC based temperature sensor module operates on 5V and has a DO or AO output. Temperature sensing ranges from 25 to +80 degrees Celsius. For water resistance, the thermocouple is coated with black epoxy. The analog DC output of an AO is proportional to the temperature. The output form of this module is DO for digital switching outputs (0 and 1) and AO for analog voltage output. The thermistor module is temperature sensitive and is commonly
