Ai Thinker Rd-04 10GHz Radar Sensor


Package Includes

  • 1x Ai Thinker Rd-04 10GHz Radar Sensor Module

Availability: 26 in stock

The Rd-04 Module from Ai Thinker is a high sensitivity 10GHz human presence sensing module. Radar signal processing and accurate human body sensing algorithms allow a high level of sensitivity when detecting bodies that are either in motion or stationary – a big step up from your standard PIR sensors. Approximate distance to the target can also be calculated using the data received from the radar sensor. Reaching up to a maximum sensing distance of 6.5 meters, this sensor is primarily used indoors to output results in real-time.
