This package includes a Sensor of Level of Water and a Sensor of Humidity from Solo. If the plates have water covering the sensor components, an analog value will be available on the "SIG" connection. The Sensor of Level of Water can detect up to 4cm of water. This way, you can check if your aquarium, or your pet's water bowl, still has enough water. You can use the Sensor of Moisture of the Soil to check your plant's soil or growing environment, for example.

LDR Light Sensor with Relay

With this Adapter Board the standard 10PIN AVRISP USBASP STK500 can be used to interface with the standard 6PIN interface converter. AVR MCU development board can be used to download interface converter. The development board can be used for the ISP interface converter.

SD Card Shield Arduino

Acrylic Transparent Plate for Arduino UNO R3.

Uses the NTC Thermistor Sensor, Good Sensitivity. The Clean Waveform of the Comparator Output Signal is Good, Driving Capacity.

The KY039 Infrared Pulsation Sensor is a small, inexpensive plate used to measure the electrical activity of the heart to enable heart rate / pulse checking in different parts of the human body. The data presented by the Sensor is useful for formulating exercise routines or even for studying and verifying heart activity levels.

The Rotary Encoders are similar to Potentiometers, however, as they have no physical limits, they can run indefinitely. However, the similarity to a potentiometer is only physical, instead of having a variable resistance, in this type of Encoder we have an impulse output with 20 impulses per turn. In addition to the impulse output, it also has a push button function with two dedicated pins that close when we press the Encoder shaft.

The imported PL2303HX controller can stabilize the flash at high speed. With a 500mA auto-recovery fuse for protection and two data transmission indicators that can monitor the data transfer status in real time. The entire board is coated with a high-quality transparent heat-shrinkable layer, rendering the PCB in a state of isolation from the outside, so that the board is not burned. Electrostatic package, ensures that the plate will not be damaged before use. Supports WIN7 system.

USB cable A for Mini USB with 1.8M, from Biwond, of great quality. It is compatible with digital cameras, GPS and other devices, such as the Arduino Nano.

This Module of Switch Reed uses a Small Device called a Leaf Switch. When the Device is Exposed to a Magnetic Field, the Two Ferrous Materials within the Switch are joined together and the Switch closes. When the Magnetic Field is Removed, the Switch Opens.

Header Socket with 10-pin female ideal for PCB's or Arduino.
