Hi. I've purchased the Liquid Level Sensor from Cytron here: http://cytron.com.my/viewProduct.php?pc ... l%20Sensor
And here's the datasheet (different from Cytron product page, because the sensor is updated): http://www.milonetech.com/uploads/eTape ... 15TC-8.pdf
I read from the Cytron product page that the connection is simply like using a potentiometer to microcontroller (i use Arduino Uno, if that matters). I've tried connect a 10k POT to Arduino, with +5V, analog pin and GND to the POT and it works. Reading the analog input is from the serial monitor where it produced 0-1023 value.
The problem here is, by using the same connection, i cannot make the water level sensor to works! I even tried some other connection, but still cannot. The serial monitor just produced 0 all the time.
Here is the front picture of the sensor:
And here is the sample circuit taken from the datasheet.
From the datasheet, Rsense is pin 2 & 3 while Rref is pin 1 & 4. From Arduino, i connect +5V to pin 1 of the sensor, analog A0 to pin 2, and GND to pin 3. Am i doing it right? Because it's not working. Please, any help would be much appreciated!
