If you want to build a device that is used to detect sense motion and almost always used to detect whether a human has moved in or out of the sensors range. Then this Sensor is needed for you. you can buy this sensor from Robu.in at a reasonable price
The PIR Motion Sensor Detector Module HC SR501 allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor’s range. It is often referred to using “PIR”, “Pyroelectric”, “Passive Infrared” and “IR Motion” sensors.
The module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It has a delay time adjustment Potentiometer and sensitivity adjustment Potentiometer. Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc.

If you are want to make a device that is used to detect Ammonia, Sulphide, and Benzene steam, also sensitive to smoke and other harmful gasses from the desired distance, then this sensor is needed for you.y0u can buy this sensor from Robu.in at a reasonable price.
The MQ 135 Air Quality Detector Sensor Module For Arduino has lower conductivity in clean air. When the target combustible gas exists, the conductivity of the sensor is higher along with the gas concentration rising.
Convert the change of conductivity to the corresponding output signal of gas concentration. The MQ135 gas sensor has a high sensitivity to Ammonia, Sulphide, and Benzene steam, also sensitive to smoke and other harmful gases.
It is at a low cost and suitable for different applications such as harmful gases/smoke detection.
