Aoicrie DHT11 Temperature Humidity Sensor Module Digital Single Bus 3.3V-5V with Jumper Wires for Raspberry Pi
Product description DHT11 Temperature and Humidity Sensor Module for Arduino Raspberry Pi 2 3 Specifications: Power supply voltage: 3.3~5.5V DC Output: the single bus digital signal Exchangeability: fully interchangeable Sampling interval: 2 seconds or more Communication distance: up to 20M 2.54mm pitch 3P connection Pin header mounted Temperature Resolution: 1 °C Accuracy: ± 2 °C Measurement range: 0-50 °C Humidity Resolution: 1% RH Accuracy: ± 5% RH (0-50 °C) Measurement range: 20% RH-90% RH Recommended Storage Environment Temperature: 10-40 °C Humidity: less than 60% RH Interface Description: 1.VCC:External 3.3 V-5 V 2.GND:External GND 3.DO:Small board switch digital output interface, connect the microcontroller IO port Operating specification (1) Power and Pins Power's voltage should be 3-5.5V DC. When power is supplied to sensor, don't send any instruction to the sensor within one second to pass unstable status. One capacitor valued 100nF can be added between VDD and GND for power filtering. (2)Communication and signal Single-bus data is used for communication between MCU and DHT11. Small size & low consumption & long transmission distance enable DHT11 to be suited in all kinds of harsh application occasions. Packing Included: 1 x DHT11 Temperature and Humidity Sensor Module 1 x Jumper Wire
Product Features
- DHT11 digital temperature and humidity sensor is a digital signal output with a calibrated temperature and humidity combined sensor.
- It uses a dedicated digital modules and acquisition of temperature and humidity sensor 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.
- The digital signal is fairly easy to read using any microcontroller. Accuracy: Humidity +&-5% RH, temperature +&-2 celsius degree. Humidity measuring range: 20% - 90% RH, Temperature measurement range: 0 to 50 C.
- Since the sensor can be operated with both 3.3V and 5V, it is suitable for connection to all standard boards, RN-Control, for Raspberry Pi and all other microcontrollers.
