How to deliver data of sensor to the cloud platform(LinkNode D1)

Recommended Posts




DHT22 module applies specific digital blocks collection technology and temperature and humidity sensing technology to ensure that products with high reliability and excellent long-term stability. Sensor comprises a capacitive humidity sensing element and a high-precision temperature component, and with a high-performance 8-bit microcontroller connected. Therefore, the product has excellent quality, fast response, anti-interference ability, high cost and so on.  Measurable temperature range of the module: -40-80 ℃ ± 0.5 ℃, humidity range: 20-90% RH ± 2% RH. The module is widely used in temperature and humidity regulator, weather station, and other relevant temperature and humidity detection control.

Material preparation

  • LinkNode D1 x 1
  • DHT22 x 1
  • DuPont line
  • Arduino IDE


1. Login  linksprite.io ,record the “Device ID” and “API key” ( If there is no account, please sign up. )
