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

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

Descrtion:

1. 100% 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 r, 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 r to create an automatic watering system, so your garden plants need someone to manage it. Parameter: 1. Using sensitive photosensitive resistance r 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 og 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 photo module is the most sensitive to ambient light, and is generally used to detect the brightne of the ambient light, trigger the single-ch 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-ch microcomputer, and the high and low level can be detected by the single-ch 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 og 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; Paage list: 1 x Light brightne r 1 x Soil moisture r 4 x Dupont line
