The item is for Arduino robot kit, raindrops, rain sensor, monitoring can be used for a variety of weather conditions, and converted into the number of the reference signal and the AO output.
\nThe sensor uses the FR-04 high-quality double-sided materials, King Size 5.0 * 4.0CM, and with the surface of the nickel plating treatment, against oxidative, conductivity, superior performance and longevity;
\nThe output in the form: digital switching outputs (0 and 1) and analog AO voltage output;
\nTTL-level output, TTL output valid signal is low. Driving capability 100MA so, can directly drive relays, buzzer, a small fan, and so on.
\nSensitivity can be adjusted via potentiometer
\nLED lights up when there is no rain output is high, raindrop up, the output ground level, LED light.<\/p>\n

\nDistribution bit to adjust sensitivity
\nA fixed bolt hole for easy installation
\nPower indicator, the output signal LED indicator
\nThe comparator output, the signal is clean, waveform, driving ability over 15mA
\nWide voltage LM393 comparator
\nA large area of ??rain board, more conducive to detect rain
\nBoard with positioning holes to facilitate installation.<\/p>\n
\nConnected to 5V power supply, the power indicator light, sensor board is not water droplets, DO output is high, the switch lights off, dropping on a drop of water, DO output is low, the indicator light switch,
\nBrush off the the above water droplets, has returned to output high state. . . .
\nAO analog output can be connected to the microcontroller AD port to detect the size of the drops in the above rainfall.
\nDO TTL digital outputs can also be connected to the microcontroller detects whether there is rain.<\/p>\n","protected":false},"excerpt":{"rendered":"
