<p>The KY-018 Photo resistor module is made up of a small printed circuit board measuring 20x15mm, fitted with a 3-pin pin header, a 5mm diameter photoresistor and a resistor. The photoresistor is part of a voltage divider, the light, by varying the total resistance, modifies the output voltage which can be measured via one of the Arduino A / D pins.<br />For more information see <strong><a href="...
<div>The KY-035 Analog Hall magnetic sensor module is part of the "37 In 1 Sensor Module Board Set Kit For Arduino" series, it is a Hall sensor, the module is very similar to the KY-003 Hall magnetic sensor module, but the latter has an ON / OFF digital output, while the one described on this page provides an analogue output signal. The value varies with the intensity of the magnetic field.<...
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, th...
The main component of the KY-008 Laser sensor module is represented by a laser diode that emits a low power red laser beam.
Its absorption is only 30 mA, so in line with the maximum the rated current that an Arduino digital pin can provide equal to 40 mA.
