Hello ,

I want to know if it is possible to use analog temperature sensor or analog humidty sensor with TELTONIKA FMB120 ( pin AIN1 and AIN 2 ) to measure temperature and humidity ?

Thank you very much.

Cordially.

Dear Mr. Imad,

we have different solutions for this.

First we have bluetooth sensors for temperature and humidity

Acquiring datas once every 15 minutes lets sensor's battery last 1 year. Battery is standard one and can be changed. 
Battery level can be acquired together with values.


Second possibility is to use analog sensors .
Below analog sensors specs

Analog Input:
  • Input voltage (Recommended Operating Conditions), Range 1: 0 +10 V
  • Input resistance, Range 1: 150 kΩ
  • Measurement error on 12V, Range 1: 3 %
  • Additional error on 12 V, Range 1: 360 mV
  • Measurement error on 30 V, Range 1: 3 %
  • Additional error on 30 V, Range 1: 900 mV
  • Input Voltage (Recommended Operating Conditions), Range 2: 0 +30 V
  • Input resistance, Range 2: 150 kΩ
  • Measurement error on 12V, Range 2: 3 %
  • Additional error on 12 V, Range 2: 360 mV
  • Measurement error on 30 V, Range 2: 3 %
  • Additional error on 30 V, Range 2: 900 mV


Of course tracker will send to server analog values in mV and you'll have to scale accordingly.
