If you like WiFi communication, especially with ESP8266 chips, you can't miss this kit that includes several modules such as sensors, button, LED, Display, Relay, protoboard, among others. And you couldn't miss the respective ESP8266 D1 Mini v3 to be able to program in an Arduino environment and develop your wireless and IoT projects.

The Atlas Scientific pH circuit designs currently available on the Internet are outdated and use a significant number of overly complex analog components. Atlas Scientific has reinvented and refined the pH circuit of the past to a more modern and simple to use model.

The BME280 Atmospheric Sensor from Whadda is the easiest way to measure barometric pressure, humidity and temperature.

Grove's capacitive humidity sensor (corrosion resistant) is a soil moisture sensor based on changes in capacitance. Compared to resistive sensors, capacitive sensors do not require direct exposure of metal electrodes, which can significantly reduce electrode erosion.

DHT22 is a digital capacitive humidity sensor and humidity module is one that contains the compound has been calibrated with digital signal output from the temperature and humidity sensors . < / p>

This Flame Sensor is sensitive to the flame, but also can detect ordinary light. Usually used as a flame alarm. 

Electronic Brick - Soil moisture sensor is mainly used to detect soil moisture content . The module can obtain the soil moisture value or limit through analog or digital pins.

The Kit Set of Torix Connectors is widely used in building wiring. By selecting the best insulation material, it is durable, corrosion free, anti-aging, pressure 4kv and against electric shock. It breaks the disadvantage of the traditional wiring method which is problematic in wiring, easy to leak, and easy to corrode.

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