Description

Six single-wire temperature and humidity sensors on TinkerBlock boards: three precise DHT22s and three basic DHT11s. Both share the same pins and library.

Highlights

• Two grades in one box. Use a DHT22 where accuracy matters and a DHT11 for basic indoor monitoring.
• Three wires. GND, VCC and DATA, with the 10 kΩ pull-up already fitted.
• Runs at your logic voltage. Works with 3.3 V and 5 V boards.

In the box

• 3 × DHT22 module on the TK39 board, white cage, −40 to 80 °C
• 3 × DHT11 module on the TK38 board, blue cage, 0 to 50 °C
• 1 × storage case

Specifications

• DHT22 range: −40 to 80 °C, 0 to 100 % RH
• DHT22 accuracy: ±0.5 °C, ±2 % RH
• DHT11 range: 0 to 50 °C, 20 to 80 % RH
• DHT11 accuracy: ±2 °C, ±5 % RH
• Supply: 3.3 to 5 V (DHT22 up to 6 V)
• Interface: Single-wire digital

Works with

Arduino, ESP32 and other microcontrollers with a DHT library.
