Description
The Point Sensor Temperature sensor is a battery
operated digital temperature sensor with a microprocessor controlled 418 MHz
or 900 MHz. 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.
