## Description

The DHT20 temperature & humidity sensor is the newly upgraded version of the DHT11. Data accuracy, stability, response speed, measurement range are greatly improved up. DHT20 is a brand new ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor element and a standard on-chip temperature element. All sensors are factory calibrated and characterized by low power, high precision & stability, fast response, and strong anti-interference. Moreover, the DHT20 performance parameters of accuracy, power supply voltage, measurement range and response time have been enhanced greatly over the previous generation, making it more cost-effective. Besides that, the DHT20 temperature & humidity sensor employs I2C digital output protocol, which is very suitable for HVAC, automobiles, data loggers, weather stations, home appliances, and other related temperature and humidity detection and controlled areas.Factory calibrationI2C digital outputQuick response, strong anti-interference abilityLow power, low costCompatible with mainboards like Arduino, micro:bit, ESP32, Raspberry PiCompatible with 3.3~5.5V main controllerHVACAutomobilesData loggersWeather stationsHome appliances SPECIFICATION Operating Voltage: 3.3V ~ 5.5V DCOperating Current: ＜1mAOutput Signal: I2C (0×38)Temperature Range: -40 ~ +80°C ±0.5°CHumidity Range: 0~100%RH ±3%RH (25°C)Resolution: 0.01℃, 0.024%RHStorage Condition: 10℃-50℃, 20-60%RHBoard Dimension: 22*33 mm/0.87*1.30”Mounting Hole Size: Inner diameter 3.1mm (0.13”)/Outer diameter 6 mm (0.24”) DOCUMENTS Product wiki SHIPPING LIST Temperature and Humidity Sensor x1Gravity-4Pin I2C Sensor Connector (30cm) x1
