Product Description

DHT11 Temperature and Humidity Sensor

= Calibrated Digital Sensor for Arduino and DIY Projects =

The DHT11 is a low-cost digital sensor combining temperature and humidity measurement in a single component. It provides calibrated digital output, making it ideal for weather stations, home automation, and educational projects .

Simple Digital Output Singlewire communication with factory-calibrated readings
Low Power Consumption 11.5mA during measurement, 40-50µA standby for battery projects
Supply voltage is 3.3V to 5V - compatible with Arduino, ESP32, and Raspberry Pi
Use a 10kΩ pull-up resistor on the DATA line for stable readings
Measurement range is limited to 050°C and 2090% RH - not suitable for extreme conditions

= Troubleshooting =

No readings:

  • Verify 3.3V to 5V power supply
  • Check DATA pin connection and pull-up resistor
  • Allow 1-2 seconds between read requests

Inconsistent data:

  • Add 10kΩ pull-up resistor on DATA line
  • Keep sensor away from direct heat sources
  • Check wiring for loose connections
