NH3 Sensor

Introduction

♦  The working principle of NH₃ Sensor is measuring concentration of gas by using electrochemistry. The probe consists of electrode and electrolyte. The electrolyte is separated by a selective gas-permeable membrane. The gas diffusing in sensor occurs redox reaction on the surface of electrode. Current is generated in the electrode. The value of current is corresponding to the concentration of gas. Sensor converts the signal in electrode into analog signal.

Usage

♦  Connect NH₃ Sensor to any port in SenseDisc.

♦  Expose NH₃ Sensor electrode in the air with NH₃ to collect data.

Notes

♦  The electrode is gas-permeable membrane electrode. Try not to break the membrane when assembling the device. 

♦  NH₃ is poisonous. Be careful and take precautions during using.

Typical experiment

♦ Detect concentration of ammonia gas
