Description:
The Point Sensor Temperature/Humidity sensor is a battery operated temperature and humidity sensor with a microprocessor controlled 418 MHz. FCC certified radio transmitter. The Point Sensor Temperature/Humidity 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, linearized temperature, linearized and temperature compensated humidity data are combined with a CRC-16 error check and transmitted in a very short data packet that results in a very short transmitter on-time. This architecture allows the Point Sensor Temperature/Humidity sensor to consume very low energy resulting in a battery life of up to 3 years.
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 Temperature/Humidity can be turned off by re-inserting the battery pull tab or by removing the battery.
