Topic: Usage of Voltage-Sensors (practical sample)
Hi dear Wialon Users,
just got an angry mail from an customer that our hardware is always consuming to much power and that they could not start the cars after weekend.
as we know, that this could not be (hardware consumes 48mA per hour) we just added a "analog" sensor in Wialon which uses the parameter of power supply in our hardware. than i created an report which shows me the voltage of the main battery of the car (=powersupply).
On first car we could see, that the car was not used nearly 2 weeks (which consumed round about 13Ah, if you calculate that there are also some other "standby" devices in the car which consumes a bit power this is for an 6 years old batterie absolut normal that it doesn want to start after that
on second car we could see, that power-voltage drops even after weekend from 12,3volt to 11,8 Volts and after 4 Days below 10 Volts.
= battery is bad.
Nice or? just 2-3 clicks and you know if your customer just makes bla bla.
