4.1.6 CO2 and Temperature sensor
The sensor comes factory calibrated, but when recalibration is needed it can be done in the following steps:
1) Screw out top part of the sensor;
2) Small dipswitch on the PCB board should be set in MAN position;
3) Press and hold CALIBR. button till red LED starts to blink;
4) Now sensor should be left in the fresh air outdoor environment during the calibration process for 30
minutes without any person nearby.
5) When the calibration process is finished, screw on the sensor's top part back.
4.1.7 Pulse Counter sensor
The sensor counts the number of mechanical contact closes. The applications include electricity meters,
water flow monitoring etc. Both count-per-measurement interval and the cumulative count are registered.
The SensorHub software can convert and represent these measurements in the preferred metric (Volume,
Current, Torque etc.) and preferred units (liters, joules, watt-hours etc.).
