Rain Drop Sensor Module
We have ✅ 14 available of the LB-24-RAIN in our Sydney warehouse.
A raindrop module can detect when it rains and measure the rainfall intensity.
There are four pins at the bottom:
3.3V : 'VCC' stands for Voltage Common Collector, we'll connect the VCC pin to 3.3V on the micro:bit
GND: In electronics, we define a point in a circuit to be a kind of zero volts or 0V reference point, on which to base all other voltage measurements. This point is called ground or GND.
Digital Output (DO)
Analog Output (AO)
Voltage is the difference in potential between two points. As it is difficult to talk about voltage without a reference point, we need another point to compare it to.
There are also two pins at the top that connect to the second part of the raindrop sensor module. One end connects to ground and has a symbol next to it, that looks like a horizontal version of ⏚
The Rain Drop Sensor Module appears in the following collections:
