Point Sensor Counter/Temperature 418 MHz Digital Counter and Temperature Sensor Main Features
|
 |
|
Description: The Point Sensor Counter/Temperature wireless transmitter is a battery operated digital counter and temperature sensor with a microprocessor controlled 418 MHz. FCC certified radio transmitter. The Point Sensor Counter/Temperature 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, status, counter data, and temperature are 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 Point Sensor Counter/Temperature to consume very little energy and a battery life of 2 to 4 years results. The electronics are coated with a conformal material that provides a moisture barrier against condensation. Submersion in water is not recommended. A button on the top of the ABS cover permits a user to activate the service switch. 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 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 removing the battery pull tab to engage the battery. The Point Sensor Counter/Temperature can be turned off by re-inserting the battery pull tab or by removing the battery.
