Ammonia probe Sensors Arduino Forum

· They do tend to be quite expensive though, an ISE for ammonia looks to be 500 to 1000. And some of those membranes don''t last long and almost none can stand up to constant monitoring. There are ammonia gas sensors that are supposed to be pretty accurate and if the OP knows his basic chemistry he may be able to exploit one of those. Should be ...

LM35 Temperature Sensor Arduino Tutorial (3 Examples)

However, this function will not actually return the output voltage of the sensor. Arduino boards contain a multichannel, 10bit analog to digital converter (ADC), which will map input voltages between 0 and the operating voltage (5 V or V) into integer values between 0 and 1023. On an Arduino Uno, for example, this yields a resolution between readings of 5 volts / 1024 units or, ...
