The Point Sensor Thermistor wireless transmitter is a battery operated 10K ohm thermistor interface with a microprocessor controlled 418 MHz, 433 MHz, or 900 MHz FCC certified radio transmitter. It 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 is read from a Dallas Semiconductor 1-wire digital device and thermistor data is read from a 12-bit analog to digital converter. This information is 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 sensor to consume very low energy resulting in a battery life of up to 2 years (900 MHz) or up to 10 years (418 MHz & 433 MHz).
 
The electronics are coated with a conformal material which provides a moisture barrier against condensation. Submersion in water is not recommended. The service switch is activated by a pushbutton (418 MHz & 433 MHz), or by a magnet (900 MHz). 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 pushbutton under the center of the enclosure top (418 MHz) or by momentarily placing the magnet next to the "Service" label located by the Phoenix connector (900 MHz). When the sensor is started, 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 (418 MHz & 433 MHz) or reed switch with magnet (900 MHz) is 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 from the manufacturer.) To enter this powered down state, push and hold the pushbutton under the center of the enclosure top for 5 or more seconds (418 MHz & 433 MHz), or place the magnet near the "Service" label for 5 or more seconds (900 MHz).
