Grove - Starter Kit for Arduino

SONOFF SNZB-02 is an elegant mini wireless intelligent temperature and humidity sensor via ZigBee, through its Bridge(required). Program and create scenes based on the detected values. Maintain a stable temperature in your home.

Level sensor for liquids with float. The liquid level sensor acts as a switch. Liquid level float sensors are used when constant control and regulation of the liquid level (water, oil and other fluids) is required such as extraction pumps. The sensor is equipped with a float with a magnet which, acting by the buoyancy force of the fluid, moves along the tube, shortening or opening the reed switch. It can be used to detect liquid levels that are too high or too low. Ideal for all those applications where the level of non-corrosive liquids such as water tanks or aquariums needs to be monitored. It is made of stainless steel.

This small 10-DOF sensor module GY-91 is more compact than the GY-80 module.
The module uses a unique MPU-9250 chip combination with built-in 3-axis gyroscope, 3-axis accelerometer, digital compass and BMP280 enhanced barometric pressure sensor.
The MPU-9250, delivered in a 3x3x1mm QFN package, is the smallest 9-axis MotionTracking device in the world and incorporates the latest InvenSense design innovations, allowing dramatically reduced chip size and power consumption, while improving the performance and the cost. Enhancements include low-power accelerometer mode support with only 6.4μA of and provides improved 16-bit compass data resolution (0.15 μT per LSB).

It consists of three principles of induction of primary colors, if you know the composition of all types of color values, you can know the color of the test object.
For TCS230, a color filter is chosen, only a certain primary pass is allowed, it is stopped by another color. For example, when choosing a red filter, the incident light can only be stopped in red, blue and green, so you can get the intensity of the red beam of light.
For the same reason, the choice of other filters, can obtain the intensity of blue light and green light.
Through these three values, the color of the light can be projected onto a TCS230 sensor. Color Recognition Sensor GY-31 TCS230 TCS3200 features:
- Operating voltage: 3 - 5 VDC
- Model GY-91
- Chip TCS230 TCS3200

Holder for ultrasonic, distance meter HC-SR04. Ideal for installing the sensor on mobile platforms such as robots, vehicles, etc.

Sensor used for measuring of the object acceleration in 3 axis in the range of either ±2g, ±4g or ±8g. It is powered with 1.95V to 3.6V. What sets this module apart is its user-friendliness, compatible size and low power consumption. it comes with headers attached

It is a version without headers of a popular BOB-09868 from SparkFun.

In our offer, we have a versuib with headers (SP0001) and with QWIC system (SP0005).

The MAX9812 is a sound amplifier specially designed to treat the signal coming from microphones.
We can use it together with Arduino to measure sound from a processor like Arduino.
When we saw the modules with microphone we commented that, in general, the signal generated is too low to be registered correctly.
If we want to be able to measure sounds, we will have to amplify the signal. The MAX9812L has single / dual inputs, fixed gain of 20dB, bandwidth of 400 kHz, low noise and low signal distortion 0.015% THD.
There are two models, its supply voltage is 2.7V to 3.6V.
We can use the sensors with MAX9812 for applications that require measuring the intensity or frequency of the sound.

It is very easy to make it work with an Arduino, PIC or any other microcontroller.
In its output pin we can measure the pulse width PWM depending on the distance of the obstacle.
Mounting bracket is ideal for installing the sensor on mobile platforms such as robots, vehicles, etc. HC-SR04 + Ultrasonic Sensor Support Arduino features:
