Wireless People Counter BlackThe PRx20W1 – PTx20-1 is a battery powered bi-directional wireless people counter set.
The principle is based on the interruption of a horizontal infrared beam. The transmitter PTx20-1 transmits the infrared beam to the receiver “PRx20W1”. When this infrared beam is interrupted, e.g. by a person, the receiver will detect this and will increase the internal counter. The PRx20W1 is direction sensitive, which means that counts in both directions are stored separately.
Count values are available within one minute. Distortion or a blocked counter is also reported.
Because of the innovative use of electronics, the counter can run for approximately 1 years on one set of batteries, without compromising the counting distance.

The sensor data will find its way to the server through the gateway SNG10E or SNG3G. And thus the sensor data will be connected to the internet of things.

No software installation is needed when using the IMMotion Cloud. The IMMotion Cloud allows you to get insight in the number of visits of your shop, toilets or any other place where you want to count the number of people.
