Gravity: DHT20 Temperature & Humidity Sensor for Arduino

The DHT20 temperature and humidity sensor is the newly upgraded version of the DHT11. It offers significant improvements in data accuracy, stability, response speed, and measurement range. It features a brand - new ASIC dedicated chip, an enhanced MEMS semiconductor capacitive humidity sensor element, and a standard on - chip temperature element. Factory - calibrated, it has low power consumption, high precision and stability, fast response, and strong anti - interference ability. Compared to the previous generation, its performance parameters such as accuracy, power supply voltage, measurement range, and response time are greatly enhanced, making it highly cost - effective. The DHT20 uses the I2C digital output protocol, which is well - suited for HVAC, automobiles, data loggers, weather stations, home appliances, and other temperature and humidity detection and control areas. Key features include factory calibration, I2C digital output, quick response, strong anti - interference, low power, low cost, compatibility with mainboards like Arduino, micro:bit, ESP32, Raspberry Pi, and compatibility with 3.3 - 5.5V main controllers. Specification details: Operating Voltage: 3.3V - 5.5V DC; Operating Current: <1mA; Output Signal: I2C (0×38); Temperature Range: - 40 - +80°C ±0.5°C; Humidity Range: 0 - 100%RH ±3%RH (25°C); Resolution: 0.01℃, 0.024%RH; Storage Condition: 10℃ - 50℃, 20 - 60%RH; Board Dimension: 22*33 mm/0.87*1.30”; Mounting Hole Size: Inner diameter 3.1mm (0.13”)/Outer diameter 6 mm (0.24”). Shipping includes one Temperature and Humidity Sensor and one Gravity - 4Pin I2C Sensor Connector (30cm).

Using the DHT20 temperature and humidity sensor is easy. First, connect the sensor to your compatible mainboard like Arduino, micro:bit, ESP32, or Raspberry Pi using the provided Gravity - 4Pin I2C Sensor Connector. Make sure your main controller has a voltage between 3.3V and 5.5V. Once connected, the sensor will start collecting temperature and humidity data. You can use this data for various applications such as HVAC control, automotive monitoring, or home appliance automation. When it comes to maintenance, keep the sensor in the recommended storage condition of 10℃ - 50℃ and 20 - 60%RH. Avoid exposing it to extreme temperatures or high humidity for long periods. Also, check the connections regularly to ensure a stable signal. If you encounter any issues, refer to the product wiki for more detailed troubleshooting steps.
