FTCBlock 5pcs DHT11 Temperature and Humidity Sensor Module for Arduino Raspberry Pi
Product Description
DHT11 digital temperature and humidity sensor is a calibrated digital signal output temperature and humidity combined sensor, which utilizes exclusive digital-signal-collecting-technique and humidity sensing technology to ensure that products with high reliability and excellent long-term stability.
Sensor consists of a resistive element and a sense of wet NTC temperature measurement devices, and with a high-performance 8-bit microcontroller connected.
The single-wire wiring scheme makes it easy to be integrated to other applications.And the simple communication protocol greatly reduces the programming effort required.
Accuracy: Humidity +&-5% RH, temperature +&-2 celsius degree.
Humidity measuring range: 20% - 90% RH, Temperature 0 to 50 celsius degree.
Instruction:
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.
