Temperature Sensor electronic circuit
The USB Humidity measures the relative humidity and air temperature though a hole in the middle of the housing.
The device contains a calibrated precision sensor with a measurement accuracy of ±2 % relative humidity and ±0.4°C in most part of measurement range.The size of the device is about 40 x 90 x 23 mm.
The valid temperature range for using the USB Humidity is – 20° to +80° C.
Using the sensor outside this range may destroy it.
When temperature falls below 0°C, the USB cable should not be dejected to avoid damage of the cable cover.
