BAPI Wireless 418 MHz Outside Air Temperature and Humidity
Transmitters are designed to be mounted outdoors. The UV-resistant
plastic shield keeps the sensor out of the sunlight and allows for
excellent air circulation. The Outside Air Units come with a watertight
BAPI-Box enclosure which is made of UV-resistant polycarbonate and carries an IP66 rating.

The Wireless Outside Air Temperature and Humidity Transmitter measures the temperature and
humidity and transmits the data through 418MHz RF to a receiver. It has an in-building range of 100
feet* and an estimated battery life of 8 years using two high-capacity 3.6V lithium batteries with a
transmit rate of about once every 20 seconds. Each transmitter has a unique address with built in
error detection. Each variable sent by the transmitter is picked up by the receiver and converted by a
BAPI Analog Output Module to a voltage, current or resistance signal which is sent to the controller.
