This is low cost LDR (Light Dependent Resistor). Basically it is a light sensitive resistor, the resistance will decrease when the surface is expose to light. It is widely used to detect Day or Night, example in automatic car porch light.
The MQ-7 is a handy breakout board that measures carbon monoxide in the air with great accuracy, tracking levels from 20 up to 2000 ppm. As CO levels rise, the sensor's internal resistance drops, sending an analog signal that development boards like an Arduino can easily read.
A digital hall effect sensor module combining the A3144 hall sensor with an LM393 comparator for reliable magnetic field detection.
BME280 is a high-precision, small-volume, low-energy pressure sensor that can be used in mobile devices. Its performance is excellent, the absolute accuracy can be as low as 0.2Pa, and the power consumption is very low, only 2.7uA.
Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on.
The VL53L0X V2 time-of-flight range-finding sensor is a new generation of laser ranging modules. The VL53L0X is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny invisible laser source and a matching sensor.
Next-Gen Occupancy Detection: More than just a motion sensor. The LD2410C is a high-sensitivity 24GHz millimeter-wave (mmWave) radar module designed for advanced human presence detection.
This photosensitive sensor module operates effectively within a supply voltage range of DC 3.3-5V, making it suitable for various applications and systems requiring different power levels.
Carbon dioxide is a critical indicator of indoor air quality that can affect human cognitive abilities and well-being. The SCD40/SCD41 are Sensirion's next-generation miniaturized CO2 sensors, offering high precision and cost-effectiveness.
The BME680 is a "4-in-1" sensor that measures temperature, humidity, barometric pressure, and volatile organic compounds (VOC) gas. It is a favorite for weather stations and air quality monitors
The GY-BMI160 is a highly integrated, low-power 6-axis inertial measurement unit (IMU) designed for precise motion tracking. It combines a 16-bit digital, 3-axis accelerometer and a 3-axis gyroscope into a single compact module, making it an ideal choice for space-constrained and battery-sensitive applications.
