FCC certified radio transmitter. FCC certified radio transmitter. The Point Sensor Temperature sensor has an on board time of day clock that 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 and digital temperature data are read from a Dallas Semiconductor DS18B20 digital temperature sensor.  This information is combined with a CRC-16 error check and transmitted in a very short data packet which results in a very short transmission time. This architecture allows the Point Sensor Temperature sensor to consume very low energy resulting in a battery life of up to 5 years. The electronics are coated with a conformal material that 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), 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); or by momentarily placing the magnet next to the reed switch as indicated on the product label (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 reed switch with magnet 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) for 5 seconds or more; or place the magnet near the reed switch (900 MHz) for 5 seconds or more to enter this powered down state.
