Temperature & Humidity Sensor Unit

Descriptions:

This sensor module utilizes DHT11 as the sensitive component and has a bypass capacitor and a pull-up resistor on-board. The DHT11 is a pre-calibrated digital output temperature and humidity sensor. The single-wire wiring scheme makes it easy to be integrated to other applications. The simple communication protocol greatly reduces the programming effort required.

Specifications:

  • Supply Voltage: 3 ~ 5 VDC
  • Temperature range :0-50 °C error of ± 2 °C
  • Humidity :20-90% RH ± 5% RH error
  • Interface: Digital
