The Point Sensor Wireless Temperature and Relative Humidity sensor is a battery operated digital temperature and relative humidity sensor with a microprocessor controlled 418, 433, or 900MHz. FCC certified radio transmitter. The Point Sensor Temp/Humidity sensor has an on board time of day clock which allows it to spend most of the time in a low power quiescent state. At predetermined time intervals the clock will wake up the onboard microprocessor. Unique serial number information, linearized temperature, linearized and temperature compensated humidity data are combined with a CRC-16 error check and transmitted in a very short data packet which results in a very short transmitter on-time. This architecture allows the Point Sensor Temp/Humidity sensors to consume very low energy resulting in a battery life of up to 2 years (900 MHz) or up to 5 years (418 MHz & 433 MHz).

The electronics are coated with a conformal material which provides a moisture barrier against condensation; however, submersion in water is not recommended. The service switch is activated by either inserting a special tool through a hole in the top ABS cover (418 MHz & 433 MHz), or a magnet activates an internal read switch (900 MHz). The Sensor is shipped with the transmitter turned off (anytime the Sensor is to be shipped the transmitter should be turned off or must be placed in a shielded container to prevent interference that might cause shipping problems). Start the Sensor by either momentarily pushing the service switch, you will feel the button click (418 MHz & 433 MHz); or by loosening the lid screws, removing the battery pull tab, and then swiping a magnet across the enclosure on the side opposite the antenna (900 MHz). When the Sensor starts, a data transmission occurs immediately and a special mark is introduced in the ID field of the transmitted data packet to indicate which sensor is in service or installation. The service switch and the battery pull tab are also used to put the Sensor in a quiescent mode (no transmissions and very low power consumption). This is the state the Sensor is in when you receive it from the manufacturer. Push and hold the service switch (418 MHz & 433 MHz) for 5 seconds or more; or remove the batteries or reinstall the pull tab (900 MHz) to enter this powered down state.
