Dear Mr. Imad,
we have different solutions for this.
First we have bluetooth sensors for temperature and humidity
shop.marcomweb.it/en/shop-online/remote-...midity-dettagli.html
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.
