The module KY-010 Optical broken module or photo interrupter module is part of the series "37 In 1 Sensor Module Board Set Kit For Arduino" the module is formed in the front part by a Photomicrosensor type EE-SX1103 (inside which there is a couple transmitter and optical receiver), and two resistors (1 kΩ and 33 Ω) in the rear.
The sensor uses a light beam between the emitter and a detector to che...
To test the series of sensors contained in the package "37 in 1 Sensor Module Board Set" which is sold by many sites it is possible to use this shield compatible with Arduino UNO original R3 and related clones.
On the board are available many connectors that are already properly connected with the digital or analog ports of Arduino.
In fact, the card, in addition to the sensors in the "37 in 1 Sen...
The KY-032 Obstacle avoidance sensor module is part of the "37 In 1 Sensor Module Board Set Kit For Arduino" series, which is an IR photoelectric sensor for obstacle detection.
Of this type of sensors, they are available in two types: with 3 and 4 pins. The 3-pin version does not have the possibility to be enabled / disabled
By placing an obstacle in front of the transmission / reception diode, t...
The module KY-003 Hall magnetic sensor module is part of the "37 In 1 Sensor Module Board Set Kit For Arduino" module is basically a magnetic switch made by a Hall effect sensor.
A Hall-Sensor-Switch (typically a 44E) of the bipolar type is mounted on the module, and an LED and a resistor are also present.
The LED lights up when a magnetic field is detected. The negative pole is on the left at the...
Solar system power for esp8266 device like weather sensor. You need 5V 0.15W solar panel and small li-po battery for example 200mAh. Zener diode stabilizes voltage on 4.3, schottky diode give 0.15-0.2V voltage drop because 4.3V is too much for li-ion battery and prevents lekage current from battery. You can use panel also like binary(0/1) light sensor.
Keep It Simple Stupid
Not tested yet.
This is a battery powered sensor board based on the ESP8266 (ESP-12F).
By using a TPL5111 chip the battery consumption can be reduced to about 1µA when the ESP is not enabled. When the TPL5111 chip receives 5V at it's wake up pin this will turn the ESP on by enabling the 3.3V voltage regulator. At this moment you can run any program you want. If you want to turn the ESP off again you have to drive...
this is a simple **dark sensor** project that is connected to a relay which u can connect to a domestic light or fan etc. thedevice make sure that when there is light, the relay will be switched OFF and when it's in the dark, therealy is turned ON.
Infrared Sensor Module has built-in IR transmitter and IR receiver that sends out IR rays and looks for reflected IR rays to detect presence of any obstacle in front of the sensor module. The module has on board potentiometer that lets user adjust detection range. The sensor has very good and stable response even in ambient light or in complete darkness.
It is Arduino and Rasberry Pi compatible b...
The module KY-002 Vibration switch module, is part of the series "37 In 1 Sensor Module Board Set Kit For Arduino" and allows you to detect the orientation or inclination.
There are KY-002 modules in which the sensor on the board is the model SW-520 and other modules in which the sensor is the model SW-18010P, these are often referred to as "tilt switches" or "rolling sensor Ball".
