The Grove - Temperature & Humidity Sensor utilizes the upgraded version of DHT11, offering better performance than the previous generation. Featuring a capacitive sensor and built-in ADC for digital output, it provides a humidity measurement range of 5–95% RH (±5%) and a temperature range of -20 to 60°C (±2%). Known for its low cost, stability, and long transmission distance, it is an ideal choice for DIY weather stations, automatic controls, and testing systems. Key Features High Measurement Accuracy and Range: Measures humidity from 5% to 95% RH and temperature from -20°C to 60°C. Built-in ADC and Digital Output: Saves I/O resources of your microcontroller. Low Cost and High Stability: Great for students, makers, and hobbyists. Long Transmission Distance: Ensures reliable communication even in larger setups. Plug-and-Play Grove Interface: Easy to use with Arduino, Raspberry Pi, and more. Comparison: DHT11 vs DHT22 Item Grove - DHT11 Grove - DHT20 Grove - DHT22 Humidity Range 5% ~ 95% RH 0% ~ 100% RH 0% ~ 100% RH Humidity Accuracy ±5% RH ±3% RH ±2% RH Temperature Range -20°C ~ 60°C -40°C ~ 80°C -40°C ~ 80°C Temperature Accuracy ±2°C ±0.5°C ±0.5°C Note: DHT11 is more cost-effective but has a smaller range and lower accuracy compared to DHT22.
