Ultrasonic sensor for infrared sauna

The ultrasonic module controls one set of infrared emitters for one visitor. It consists of a presence sensor and a control unit connected by the supplied cable. The unit may be installed under the seats, above the ceiling, or in a nearby plant room; the sensor may be placed below the backrest emitter, in the ceiling above the seat, or in a column in front. When presence is detected, the module switches on the corresponding emitters after the set delay and turns them off shortly after the person leaves. Install one module per cabin occupant. Parameters are configured and checked via WiFi, preferably using a mobile phone.
