DFRobot Gravity DHT22 Temperature & Humidity Sensor

This is the DFRobot Gravity DHT22 Humidity and Temperature Sensor.
The compound that has been calibrated digital signal output of the temperature and humidity sensors is found in the DHT22 capacitive humidity sensing digital temperature and humidity module. To guarantee that the product has great long-term stability and high dependability, temperature and humidity sensor technologies as well as specialised digital module collection technology are applied.

The sensor is coupled to a high-performance 8-bit microprocessor and consists of wet capacitive sensor components and high-precision temperature measurement sensors. The product is reasonably priced, of high quality, responsive, and has a robust anti-jamming feature.

Standard single-bus interface for rapid and simple system integration. It is the finest option for all applications, even the most demanding ones, because to its small size, low power consumption, and signal transmission distance of up to 20 metres.
With its increased precision, the DHT22 temperature and humidity sensor can take the place of the costly SHT10 imported model. In order to meet the increased demand, it can measure the humidity and temperature of the surroundings.

The product is stable and highly reliable. The interactive impact connected to the sensing of temperature and humidity can be easily realised if it is used in conjunction with a particular sensor Arduino expansion board.

The digital humidity and temperature sensors DHT22 are made for analogue sensor interfaces. Instead of taking up the Arduino’s original digital port, the analogue port will be used as the digital. The sensor’s lines have the ability to convert analogue functions into digital ones that can be utilised using a digital connection.

Features: 

• Capacitive type with high precision
• Temperature compensation across the whole range
• Temperature and relative humidity measurements
• Digital signal calibration
• Exceptional stability across time
