The Rain/Raindrops Detection sensor module can be used for both detecting rain and for measuring the intensity of rainfall.
It includes a printed circuit board (control board) that “collects” the raindrops. As raindrops are collected on the circuit board, they create paths of parallel resistance that are measured via the op-amp. The lower the resistance (or the more water), the lower the voltage output. Conversely, the less water, the greater the output voltage on the analogue pin. A completely dry board, for example, will cause the module to output 5V.
Careful, careful, no return policy once ordered, Monitor is very fragile
I order 15.6 inch monitor with built in stand for my Raspberry PI. The issue with built in stand, is that it is so fragile that a slight movement in cables the monitor will move and it can topple breaking the LCD panel. The stand does not help monitor to be in one place, not suitable for regular use.
Be careful before ordering this product as as the company does not accept returns and has not return policy, be careful careful careful.
This is Delhi based company which is importing items from China and selling without any return policy.
