When NH 3 gas exists, t he sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. MQ137 gas sensor has high sensitivity to NH 3 gas, also can monitor organic amine such as trimethylamine, cholamine well. It can detect kinds of gases including ammonia and is a kind of low-cost sensor for kinds of applications.FeaturesIt has good sensitivity to NH 3 gas in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc.Main ApplicationsIt is widely used in domestic NH 3 gas alarm, industrial NH 3 gas leakage alarm, portable NH 3 gas detector.Technical Parameters table.1NOTE: The change of Output voltage(△Vs) is the difference value between V RL in test environment and V in clean air .Basic CircuitFig2. MQ137 Test CircuitInstructions: The above fig is the basic test circuit of MQ137.The sensorrequirestwo voltageinputs: heater voltage(V H ) and circuit voltage(V C ). V H is used to supply standard working temperature to the sensor and it can adopts DC or AC power, while V RL is the voltage of load resistance R L which is in series with sensor. Vc supplies the detect voltage to load resistance R Land it should adopts DC power.Description of Sensor CharactersNH3 AirCautions1 .Following conditions must be prohibited1.1 Exposed to organic silicon steamSensing material will lose sensitivity and never recover if the sensor absorbs organic silicon steam. Sensors must be avoid exposing to silicon bond, fixature, silicon latex, putty or plastic contain silicon environment. 1.2 High Corrosive gasIf the sensors are exposed to high concentration corrosive gas (such as H 2S, SO X , Cl 2, HCl etc.), it will not only result in corrosion of sensors structure, also it cause sincere sensitivity attenuation. 1.3 Alkali, Alkali metals salt, halogen pollutionThe sensors performance will be changed badly if sensors be sprayed polluted by alkali metals salt especially brine, or be exposed to halogen such as fluorine.1.4 Touch waterSensitivity of the sensors will be reduced when spattered or dipped in water. 1.5 FreezingDo avoid icing on sensor’s surface, otherwise sensing material will be broken and lost sensitivity. 1.6 Applied higher voltageApplied voltage on sensor should not be higher than stipulated value, even if the sensor is not physically damaged or broken, it causes down-line or heater damaged, and bring on sensors’ sensitivity characteristic changed badly.1.7 Voltage on wrong pinsFor 6 pins sensor, Pin 2&5 is heating electrodes, Pin (1,3)/(4,6) are testing electrodes (Pin 1 connects with Pin 3, while Pin 4 connects with Pin 6).If apply voltage on Pin 1&3 or 4&6, it will make lead broken; and no signal putout if apply on pins 2&4.Fig7. Lead sketch2 .Following conditions must be avoided 2.1 Water CondensationIndoor conditions, slight water condensation will influence sensors’ performance lightly. However, ifwater condensation on sensors surface and keep a certain period, sensors ’ sensitiv e will be decreased. 2.2 Used in high gas concentrationNo matter the sensor is electrified or not, if it is placed in high gas concentration for long time, sensorscharacteristic will be affected. If lighter gas sprays the sensor,it will cause extremely damage. 2.3 Long time storageThe sensors resistance will drift reversibly if it’s stored for long time without electrify, this drift is related with storage conditions. Sensors should be stored in airproof bag without volatile silicon compound. For the sensors with long time storage but no electrify, they need long galvanical aging time for stability before using. The suggested aging time as follow:Stable2.No matter the sensors electrified or not, if exposed to adverse environment for long time, such as high humidity, high temperature, or high pollution etc., it will influence the sensors’ performance badly. 2.5 VibrationContinual vibration will result in sensors down-lead response then break. In transportation or assembling line, pneumatic screwdriver/ultrasonic welding machine can lead this vibration. 2.6 ConcussionIf sensors meet strong concussion, it may lead its lead wire disconnected. 2.7 Usage Conditions2.7.1For sensor, handmade welding is optimal way. The welding conditions as follow: ● Soldering flux: Rosin soldering flux contains least chlorine ● homothermal soldering iron ● Temperature ： 250℃ ● Time：less than 3 seconds2.7.1If users choose wave-soldering, the following conditions should be obey: ● Soldering flux: Rosin soldering flux contains least chlorine ● Speed: 1-2 Meter/ Minute● Warm-up temperature ：100±20℃ ● Welding temperature ：250±10℃●One time pass wave crest welding machineIf disobey the above using terms, sensors sensitivity will be reduced.。
