This device is a battery operated temperature sensor (via external thermistor) with a microprocessor controlled radio transmitter. It spends most of it's time in a low power quiescent state. At predetermined time intervals the microprocessor will wake up for 15ms to transmit a short data string to a remote receiver (Sensor Server). The data string contains the device type, unique serial number, current value and CRC-16 data integrity check. A tamper-resistant switch allows the user to activate or deactivate the sensor if necessary. When used together with a PCW-SSRX Sensor Server, multiple sensors can be monitored using any web browser or with Server Manager Software. Near real time or historical data can be retrieved from one or more facilities by one PC located on a WAN/LAN (Network) using Ethernet (TCP/IP) or directly to a PC using serial (RS232) communication (for more information please request a Sensor Server Brochure). Server Manager Software can be used to configure and manage hardware, gather and report on data, and send automatic notifi cation of sensor values.
