3.3-5V Soil Hygrometer Humidity Detection Module Moisture Water Sensor Soil Moisture With Probe Dupont Cable For DIY Kit

3.3-5V Soil Hygrometer Humidity Detection Module Moisture Water Sensor Soil Moisture With Probe Dupont Cable For DIY Kit

Descrtion:

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. Equped with adjustable potentiometer to adjust the brightne 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. Equped with fixing bolt holes for easy installation 7. Small board 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 brightne of the ambient light, trigger the single- microcomputer or relay module, etc.; 2. When the module's ambient light brightne does not reach the set threshold, the DO terminal outputs a high level; when the external ambient light brightne exceeds the set threshold, the DO terminal outputs a low level; 3. The DO output terminal can be directly connected with the single- microcomputer, and the high and low level can be detected by the single- microcomputer, thereby detecting the change of the light brightne 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 oained; Package list: 1 x Light brightne sensor 1 x Soil moisture sensor 4 x Dupont line
