Water Droplet Sensor Ready Stock : 1 Unit Harga Rp. 75.000 (kontak untuk ketersediaan Stock) harga diluar ongkos kirim Isi Paket 1x Modul Sensor + Board 1x Free Cable Product Description Voltage: 5V Have power indicator, output signal LED indicator. TTL-level output, TTL output valid signal is low, drive capacity at 100MA, can directly drive relays, buzzer, a small fan, and so on. Sensitivity adjustable via potentiometer The output is high LED light up when no rain, and vice verse. Raindrops board and the control panel is separate, convenient line leads. A large area of raindrops board, more conducive to rain detected. Board with positioning holes to facilitate installation Control panel board size: 3 * 1.6 cm The raindrop detection plate large area 5.4 * 4.0 cm Usage Connected to 5V power supply power lights, induction board no water droplets DO output is high, the switch indicator lights off, dropping on a drop of water, DO output is low, the switch i...

Harga Rp. 30.000 (harap kontak untuk cek ketersediaan produk) harga diluar ongkir Isi Paket 1 DHT11 Humidity and Temperature Sensor Specification: Dimension 28mm*12mm*10mm Main chip DHT11 huminity sensor Voltage: DC 5V Digital output Humidity Range: 20—90%RH Humidity  accuracy: ±5%RH Temperature range: 0—60℃ Temperature accuracy: ±2℃ Temperature and humidity measurements are a nice addition to many hobby projects. The four-pin device uses a 1-wire protocol. [Rajendra] discusses the ins and outs of the communications, demonstrating the part using a PIC 16F628. It’s a snap to connect to your project, requiring VCC, GND, and a pull-up resistor on the single data line. We’ve already seen it used on at least one project, and hope to see more of this little guy in your own hacks. Documentation DHT Library Arduino
