AMT1001 Resistive humidity module, Humidity sensor

The AMT1001 Resistive humidity module is a compact humidity sensor that gives an analog voltage proportional to relative humidity, ready to read with the analog input of an Arduino, ESP32 or any microcontroller ADC. It also contains a temperature sensing element and is temperature compensated, which makes it a simple choice for climate monitoring, HVAC and greenhouse projects.

AMT1001 Resistive humidity module Specifications

• Sensing type: resistive humidity sensor with temperature compensation

• Humidity range: 20–95% RH, non-condensing
• Humidity accuracy: ±5% RH at 25 °C
• Operating temperature: 0–60 °C
• Output: analog DC voltage for humidity

AMT1001 Resistive humidity module Applications

• Room and office humidity monitoring
• Humidifier, dehumidifier and air conditioning control
• Greenhouse and storage room climate logging
• Weather stations built with Arduino or ESP32

What's in the Box

• 1 × AMT1001 resistive humidity module

Tip: Power the module from a stable 5 V supply, because the output voltage depends on it, and read it with an analog pin. Convert the reading to % RH using the voltage–humidity curve in the AMT1001 datasheet, and keep the sensor away from water droplets and condensation.
