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.
The crimper has been received on the 2nd day after placing the order. I was initially sceptical to make payment in advance but proceeded anyway. Unfortunately the dies of SN-28B were deformed. I contacted the team through WhatsApp and they replaced the dies within two days with no extra charge for shipping. The shipping speed is really great. I put the crimper to test, they really made great crimps for my automobile harness. I am great satisfied with the purchase.
Worked beautifully.
The product photos show a group of three pens. One is likely to be misled that one gets three pens for Rs.40/- but one gets only one pen for Rs.40/-. The thing that sucks is that the pen costs Rs. 40/- but shipping costs Rs 90/-. So while ordering this pen, order as many other parts/components you will need to spread out the shipping on a large number of components.
