7.1.5.2 Analog Input Application 2 – Fuel Detection (percentage of fuel)
Note:
Fuel level sensors supplied by our company are resistance-type sensors with output resistance: 0-200Ω
(ohm).
For the circuit shown on above figure, if VCC is 12V, R should be 200Ω (ohm) and if VCC is 24V then R should
be 600Ω (ohm) to make the input range to AD1 or AD2 is 0-6V.
Below formula is for calculating the fuel percentage left for this fuel level sensor:
AD value
1024* 2
– AD value
The value must be converted into decimal, for example, 0x0267 is 615 in decimal.
Percentage Left =
* 100%
7.2 Install GPS/GSM Antenna
GSM Antenna
so you can hide it in any place of vehicle.
GPS Antenna
Connect the GSM antenna to the SMA connector which is ‘GSM’ text labeled. The GSM antenna is non-directional,
Connect GPS antenna to the GPS connector which is ‘GPS’ labeled. The optimum location for the GPS antenna is
on the roof of the vehicle. The covert and GPS antenna are directional, make sure they are facing up and lying as
flat as possible. Secure them in place with glue or zip ties.
Note: Do not shield or cover the GPS antenna with any objects containing metal.
7.3 Install Microphone and Speaker (Optional)
