USING A LGHTM-01A


garryl Oct 29, 2018 04:08 AM

I have recently bought a LGHTM-01A resistive temperature and humdity sensor. I would like to hook it up to a cr800 but I cant seem to work out what code I need to do this . It outputs analog voltage signal of 0-3volts.

You will connect the two outputs from the sensors (RH and Temperature) to two single ended channels and measure the voltage output, using instructions like following

VoltSe (RH,1,mV5000,1,1,0,250,1.0,0)
VoltSe (Temperature,1,mV5000,2,1,0,250,1.0,0)

Using suitable multiplier and offset (obtained form the sensor manual), you can convert the mV readings ino RH /Temperature.
