HW-M10 Microwave Sensor Module Features The HW-M10 microwave sensor module is very accurate and widely used for motion detection in alarm and security systems. This module, like the PIR module, can detect any movement. The only difference is that instead of using radiation emitted by or reflected from objects, it uses microwave Doppler radar technology. This module has a digital output that is normally Low and becomes High (3.3V) if it detects motion and remains High for 2 to 3 seconds. ...

AD8232 ECG Module Features The AD8232 sensor can provide you to monitor electrocardiographic or ECG signals. Analyzing these signals prepares useful information about heart function, such as heartbeat rate, heart rhythm, and other information regarding the heart’s condition. This module can be connected to a microcontroller on one side and to specific parts of body on the other side using 3 special electrodes. The signal received through the electrodes can be seen in the analog output of the sensor. ...

Introduction Thermometers and temperature sensors are widely used in many sectors.

CJMCU-0201 Double Touch Sensor Features A touch sensor is a type of switch that only has to be touched by an object to operate. Touch sensors work completely similar to a switch. This sensor has two separate pads and can be used as two separate switches. Note When this switch is subjected to touch, the output voltage will be HIGH, otherwise it is LOW. Note The output current is very low (about 40 mA). If you want to connect a higher current device to this switch, you must add a rela...

XKC-Y26-V Non-contact Liquid Level Sensor Features The XKC-Y26-V Non-Contact Liquid Level Sensor is a digital output sensor that detects the presence of liquid. There is an LED on the module, which will turn on if liquid is detected, otherwise it turns off. There is also a screw on the body of the module that you can use to adjust the sensitivity of the sensor. This sensor is suitable for dangerous applications such as detection of toxic substances, strong acids, strong alkalis, etc. ...

Introduction There are different sensors and methods for determining water depth, leakage, whether a container is empty or overflowing, and rain detection. One of the easiest and cheapest methods is to use a water level detection sensor that we will discuss in this tutorial.There are some other common names for this sensor: rain sensor, water level sensor, humidity sensor, and water leakage sensor. What you will learn Operating principles of a water level sensor and how to test itInterfacing th...
