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

A Whadda Universal Temperature Sensor Mounting Kit, used for measuring indoor and outdoor temperatures, controlling the rise/fall of temperature in homes, equipment, control of temperatures in some processes, visualization of the temperature on your website, control of the temperature of your pool, etc.

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.

Now the ESP8266 D1 Mini v3 is no longer alone! 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.

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.

DS18B20 is a single-bus digital temperature sensor with features of ultra-small size, wide range of applicable voltage and measurable temperature and high resolution.

The Atlas Scientific pH circuit designs currently available on the Internet are outdated and use a significant number of overly complex analog components.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.

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.

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

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.

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>

The Earth Unit is a Sensor for measuring Humidity in Soil or Similar Materials. The Soil Moisture Sensor is quite simple to use. The two large stake-type sensors act as probes for the sensor, acting together as a variable resistance. The higher the moisture in the soil, the better the conductivity between the two, so that the sensor results in less resistance and higher GIS output.

You can read the moisture in the soil through ADC. Within this unit, there is an extra potentiometer to change the measurement range.
