CS110 Electric Field Meter
purchased and connected to the SOLAR RADIATION connector to interface
to either the CS100 or the CS106 barometric pressure sensor. Examples of
instructions to measure the LI200X solar radiation sensor or the barometric
pressure sensors are given below.
‘Measure LI200X.
VoltDiff (solar_rad,1,mV7_5,3,True,450,250,200,0)
‘Measure CS106 - “continuous” or “always on” mode = jumper installed
VoltDiff (Barom_pres,1,mV2500,3,True,450,250,0.24,500)
‘Measure CS100 every hour – “triggered” mode = on/off. Trigger or turn on by setting control port
4 (C4=green wire) high.

8.5 Measuring Air Temperature and Relative Humidity
Circular connector labeled TEMP/RH can be used to connect up an HC2S3
temperature and relative humidity sensor. Example CRBasic instructions to
measure the HC2S3 Temperature and RH are given below.
SW12 (1 ) ‘Apply switched 12 V power to the probe.
Delay (0,3,sec) ‘Warm up probe before measurements.
VoltSe (air_temp,1,mV2500,2,1,0,250,.18,-40) ‘Single-ended air temp. measure.
VoltSe (RH,1,mV2500,1,1,0,250,0.1,0)
‘Single-ended relative humidity.
SW12 (0) ‘Turn off power to the probe.
if RH > 100 and RH < 103 then
RH = 100

8.6 Measuring Wind Speed and Direction
Circular connector labeled WIND can be used to connect up various wind
sensors, including the 05103 Wind Monitor, 034B Met One Wind Sensor, and
03001 Wind Sentry. Example CRBasic instructions to measure the 05103
Wind Monitor are given below.
PulseCount (wind_speed,1,1 ,1,1,0.2192,0) 'Wind Speed.
BrHalf (wind_dir,1,mV2500,4,Vx2,1,2500,False,450,250,355,0) 'Wind Direction.
