 With screen capture network-type temperature and humidity independent alarm module (comes with sensors, can be independently controlled sound and light alarm) 
 Input response time (within the module data update rate) to 1 second simultaneous measurement of an isolated road 485, MODBUS RTU communication protocol uses two-wire RS-485 output interface with +15 kV ESD protection rate (bps) in 1200, 2400 , 4800,9600,19200,38400,57600,115200 select the optional dual-protocol communication, the customer may request a ASCII format or hexadecimal format communication protocol (only LM-420) When the command in ASCII format suitable for computer programming interface; instructions to hexadecimal format, suitable for microcontroller programming interface (only LM-420) can be set lower limits on temperature and humidity alarm (only LM-420) can set the time: months days, hours, minutes, seconds, 24 hours or AM / PM (only LM-420) can store and display the maximum and minimum temperature and humidity have value, to maintain power (only LM-420) Accuracy: temperature of 0.2; humidity for the 0.5 power supply: +7.5 ~ 30V Power consumption less than 0.1W Operating temperature range -40 ℃ ~ +85 ℃ Storage conditions -40 ℃ ~ +85 ℃ (RH: 5% ~ 95% non-condensing ) volume of 106mm × 98mm × 22mm Installation: Wall mounting holes; internal bracing bracket can also be placed in the desktop and Western Group
