This is a simple moisture sensor can be used to detect soil moisture, when the soil water, the sensor output of the analog value will be reduced, and vice versa will increase. Use this sensor to make an automatic watering device. When you are not at home or after a long time, it can sense if your plant is already thirsty. To prevent the plants withered to know that is caused by water. With the Arduino controller to make your plant more comfortable, the garden is more intelligent.
The sensor surface is metallized to extend its use of time. Insert it into the soil and then use the AD converter to read it. With its help, the plant will remind you: I want to drink water, please give me a little water to drink.
Supply voltage: 3.3V or 5V
Operating current: less than 20mA
Output voltage :0-2.3 V [2.3V is completely immersed in water] voltage, 5V power supply, humidity, the greater the output voltage increases.
They don't have the right item but when customer call for replacement they will say they don't have for this statement they will hold the customer call they will put in mute later they will say they don't have all are faulty item I've ordered for micro SD to micro SD but they have shipped SD to SD they are not ready to listen to the customer need also.
It is a great product for what it offers. The digital zoom is where it falls short in its clarity being digitally zoomed, but not very bad.
The optical lens is is brilliant.
Overall a great product at this price point.
