IR-Light-Barrier with Radio Transmission

PKI 7415Print

This solar-powered unit is totally independent from any external power supply or batteries. The PKI 7415 consists in a combination of a transmitter in the IR-range and a receiver in the HF range. The IR beam has to be placed in face of IR receiver within a max. range of 300 m. In case the invisible IR-beam is disconnected e.g. by a person, an alarm will be given which will be transmitted wireless to the HF receiver up to 1 km range. The complete system is solar-powered and even without sunlight works up to 4 weeks due to built-in rechargeable batteries.
