Motion Detectors

Buy on Amazon Find on eBay

The microwave motion sensor is a microwave moving object detector designed by the principle of Doppler radar. Unlike ordinary infrared detectors, microwave sensors detect the movement of objects by detecting the microwaves reflected by the object. The detection object will not be limited to the human body, but there are many other things.

Non-contact detection; Adapts to harsh environments without affecting by temperature, humidity, noise, airflow, dust, light, etc. Powerful anti-RF interference capability; Low output power, no harm to human body; Long detection distance.

Can detects of non-living objects; The microwave moves at the speed of light with great directionality. Compatible with Raspberry Pi and Arduino Board.

Used in industrial, transportation and civil applications such as measuring, liquid levels, automatic door motion detection, automatic washing, production line material detection and car reversing sensors etc.

Note: There are ultra-high frequency MOS devices inside the microwave motion sensor. If you try to use battery power to test during the test, this can avoid the breakdown caused by the static pressure difference between the power supply and the test device, such as the oscilloscope; in addition, when the product is in use, Please try to choose battery power supply to ensure the best detection effect.

CQRobot Non-Contact Water/Liquid Level Sensor Compatible with Arduino, Raspberry Pi and Other Motherboards. for Industrial Production, Aquarium, Chemical Liquid, Agriculture, Gardening, etc.

Liquid Level Sensors

Buy on Amazon Find on eBay

The CQRobot non-contact liquid level sensor realizes non-contact detection of the liquid level in a closed container. It adopts advanced signal processing technology and high-speed signal processing chip, breaking through the influence of container wall thickness. It is simple to install and easy to use, and can detect the level of various toxic substances, strong acids, strong alkalis and various liquids in high-pressure airtight containers.

The principle is to use the inductive capacitance of water to detect whether there is liquid. When there is no liquid close to the sensor, the sensor has a certain static capacitance to the ground due to the existence of distributed capacitance on the sensor. When the liquid level slowly rises and approaches In the case of an inductor, the parasitic capacitance of the liquid will be coupled to this static capacitance, making the final capacitance value of the inductor larger.

The changed capacitance signal is then input to the control IC for signal conversion, which converts the changed capacitance into a change of a certain electrical signal, and then a certain algorithm is used to detect and judge the degree of this change. When the change exceeds a certain amount It is considered that the liquid level has reached the sensing point when the threshold is reached.

High stability, high sensitivity, strong interference ability, no external electromagnetic interference, special treatment for power frequency interference and common mode interference, strong compatibility, penetration of various non-metallic containers, such as plastic, glass, For ceramics and other containers, the sensing distance can reach more than 12mm; liquid, powder, and particulate matter can be detected.

The sensor comes with 2 DIP switches, the right DIP switch controls the output voltage (high level) of the signal terminal (green line); when the DIP switch is dialed up, the high level is 5V; when the DIP switch is facing When dialing down, the high level is 3.3V. Compatible with Arduino, Raspberry Pi and Other Motherboards.
