Description
The Point Sensor Power Monitor wireless transmitter is a battery operated 12
bit analog-to-digital converter with a microprocessor controlled 418 MHz. FCC certified
radio transmitter. The 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 is read from a Dallas Semiconductor 1-wire digital device and
analog 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
that results in a transmitter on time of only 15 milliseconds. This architecture
allows the 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. Submersion in water is not recommended.
An integral pushbutton is used to activate the service switch. 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 momentarily pushing
the service switch (you will feel the button click). When the service switch is
pushed 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 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 when you receive it from the manufacturer. Push and hold the service
switch for 5 seconds or more to enter this powered down state.
