Indoor radio temperature sensor ML-740 ZONT NS-1277523

ZONT ML-740 indoor radio temperature sensor 868 MHz ML00004436 is designed to monitor indoor air temperature and transmit measured data via radio channel at a frequency of 868 MHz. The sensor performs periodic air temperature measurements with data filtering. When the air temperature changes by more than 0.2 degrees, the sensor generates and transmits new current temperature data to the system. The information update period is once per minute if the current value changes, or once every 10 minutes if the values remain unchanged. Designed for indoor use and rated for 24/7 operation. The radio temperature sensor is used only in conjunction with ZONT ML-489 and ZONT ML-590 radio modules, which connect to ZONT and Mega SX equipment and act as transceiver devices. · Supply voltage - 3 V. · Battery type - AAA 1.5 V 2 pcs. · Battery service life - at least 3 years. · Operating frequency - 868 MHz. · Current consumption in data transmission mode - no more than 30 mA. · Current consumption in standby mode - no more than 2 μA. · Radio communication range in line of sight - at least 100 m. · Radio transmitter output power - 10 mW. · Measurement scale resolution - 0.1 °C. · Operating temperature range: -30 - +60 °C. · Enclosure - IP 20. · Error at temperature - 0 - +60 °C - no more than 0.25 °C. · Error at temperature - -20 - 0 °C - no more than 0.5 °C. · Error at temperature - -30 - -20 °C - no more than 1 °C. · Service life - 5 years. · Warranty period - 1 year.
