Sensitive material of MQ135 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, the sensors conductivity is more higher along with the gas concentration rising. Convert change of conductivity to correspond output signal of gas concentration. MQ135 gas sensor has high sensitivity to Ammonia, Sulphide and Benzene steam, also sensitive to smoke and other harmful gases. It is with low cost and suitable for different application. Used for familiar, surrounding environment noxious gas detection device. Apply to ammonia, aromatics, sulphur, benzene vapour, and other harmful gases/smoke, gas detection, tested concentration range: 10 to 1000 ppm.

This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0-3.3V ADC.

Specifications:

Requires heater voltage
Dimensions: 16.8mm diameter, 9.3 mm height without the pins

Product Details:

Voltage	5 V
Usage	Temperature Sensor
Theory	Ultrasonic Sensor

Description:

This is a simple-to-use Carbon Monoxide (CO) sensor, suitable for sensing CO concentrations in the air. The MQ-7 can detect CO-gas concentrations anywhere from 20 to 2000ppm.
This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.
This sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board

Additional Information:

Item Code: MQ7CARBONMONOXIDE
Production Capacity: 100
Delivery Time: 13DAYS
