Raindrop sensor module
50+ in stock
The raindrop sensor module is used for rain detection. It is also for measuring rainfall intensity. The module includes a rain board and a control board that is separate for more convenience. It has a power indicator LED and an adjustable sensitivity though a potentiometer. The module is based on the LM393 op-amp. 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 analog pin. A completely dry board, for example, will cause the module to output five volts.

6volt-2watt solar panel module
6volt-2watt solar panel which can deliver up to 6V, 330mA. This solar panel is ideal for space-constrained applications where small voltage is required. When operating in sunlight or a bright artificial light environment, the optical energy will activate the solar cell and generate a voltage at the output. The panel is capable of 2watts in the open sun with a peak power output of around 6V at 330mA.

1-Channel 5V Relay Module
1-Channel 5V Relay Module is a 5V 1-channel relay interface board with screw terminal, it can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM and so on. The board has a high-quality relay, which can handle a maximum of 15A at 125V or 10AA at 250V AC. Relay has three connections – Common – C, Normally Open-NO, Normally Closed-NC brought out to 3 pin screw terminals which makes it easy to make and remove connections. The board has a power indication and a relay status LED to ease debugging. Power input and relay control signals are brought to header pins on the board. Hence, the board can be easily interfaced with our development boards using our jumper wires.
