This MQ-9 gas sensor is very sensitive to carbon monoxide, methane and LPG. The sensitive material of the MQ-9 gas sensor is SnO2, which has a lower conductivity in clean air. It detects high and low temperature alternations and detects CO at low temperature (heated to 1.5V). The conductivity of the sensor increases as the…
The MQ-135 gas sensor detects gases like ammonia, nitrogen, oxygen, alcohols, sulfide, and smoke. The boost converter of the chip MQ-3 gas sensor is PT1301. The operating voltage of this gas sensor is from 2.5V to 5V. It has a lower conductivity compared to clean air and air pollution increases its conductivity. Features Sensitivity to…
This MQ4 – Methane Gas sensor module can sense the presence of compressed Natural Gas sensors (CNG), methane(CH4) etc. in the air. This is a very easy to use low-cost semiconductor Gas sensor Module with analog and digital output. It requires no external components just plug in Vcc & ground pins and you are ready to go….
MQ-7 is used for sensing CO concentrations in the air. The MQ-7 can detect CO levels ranging from 10 to 500 parts per million. This sensor has high sensitivity and a fast response time. The output of the sensor is an analog resistance. The sensor works in temperatures ranging from -10 to 50°C and consumes…
This 4-Pin NTC-based temperature sensor module operates on 5V and has a DO or AO output. Temperature sensing ranges from -25 to +80 degrees Celsius. For water resistance, the thermocouple is coated with black epoxy. The analog DC output of an AO is proportional to the temperature. The output form of this module is DO…
An infrared emitting diode (IRED) and a phototransistor are diagonally positioned in this PM2.5 GP2Y1010AU0F Dust Smoke Particle Sensor. It detects dust in the air by detecting reflected light. It is especially useful for detecting very small particles, such as cigarette smoke. Furthermore, the pulse pattern of the output voltage may distinguish smoke from house…
This is a temperature-controlled thermostat switch that uses an NTC sensor to detect the temperature to control the heating/cooling of an object. The 24V DC connected at the input terminals powers the module. The module contains two output connections, which can be used to connect equipment that will heat or cool the test system. Features:…
W1209 digital temperature controller module is a low cost and highly functional thermostat module which is widely used in automation projects. W1209 thermostat module includes a seven segment LED display and a NTC waterproof temperature sensor. There are 3 switches (SET, + and -) on board to set temperature and other parameters like turning on…
