【Ready Stock】Original Aideepen Soil Moisture Sensor Soil Moisture Meter Detection Module Smart Car

Product selling points:
1. 100% brand new and high-quality products.
2. Made of high-quality materials, durable and practical.
3. With fixing bolt holes, easy to install.
4. A soil moisture and moisture module that is more sensitive to the environment, generally used to detect soil moisture.
5. This is a summary of the humidity sensor, which can be used to detect soil humidity. When the soil is dry, the module emits a high level and outputs a low level.
6. Use this sensor to create an automatic watering system, so your garden plants need someone to manage it.

Parameter:
1. Using sensitive photosensitive resistance sensor
2. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA.
3. Equipped with adjustable potentiometer to adjust the brightness of detection light
4. Working voltage 3.3V-5V
5. Output form: DO digital switch output (0 and 1) and AO analog voltage output
6. Equipped with fixing bolt holes for easy installation
7. Small board PCB size: 3.2cm x 1.4cm
8. Use wide voltage LM393 comparator

Module instructions:
1. The photoresistor module is the most sensitive to ambient light, and is generally used to detect the brightness of the ambient light, trigger the single-chip microcomputer or relay module, etc.;
2. When the module's ambient light brightness does not reach the set threshold, the DO terminal outputs a high level; when the external ambient light brightness exceeds the set threshold, the DO terminal outputs a low level;
3. The DO output terminal can be directly connected with the single-chip microcomputer, and the high and low level can be detected by the single-chip microcomputer, thereby detecting the change of the light brightness of the environment;
4. The DO output terminal can directly drive our relay module, which can form a light control switch.
5. The small-board analog output AO can be connected to the AD module, and through AD conversion, a more accurate value of the ambient light intensity can be obtained;
