The MPU-6050 is the world’s first and only 6-axis MotionTracking devices designed for the low power, low cost, and high performance requirements of smartphones, tablets and wearable sensors.By combining a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an onboard Digital Motion Processor(DMP) capable of processing complex 9-axis MotionFusion algorithms.

The parts’ integrated 9-axis MotionFusion algorithms access external magnetometers or other sensors through an auxiliary master I2C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor.For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps) and a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g.

This soil moisture sensor measures soil mositure levels by capacitive sensing rather than resistive sensing like other sensors on the market.

It is made of corrosion resistant material which gives it an excellent service life.

Insert it in to the soil around your plants and impress your friends with real-time soil moisture data!

This module includes an on-board voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V.

It is perfect for low-voltage MCUs, both 3.3V and 5V.

For compatibility with a Raspberry Pi it will need an ADC converter.

This soil moisture sensor is compatible with our 3-pin "Gravity" interface, which can be directly connected to the Gravity I/O expansion shield.

Applications:

5A constant voltage constant current step-down module with voltage and current power display LED drive lithium battery charging with crystal case.

With USB interface, with 3 major functions, to meet your most occasions!

Module highlights:

Onboard voltage, current, power meter, you can easily use this module without a multimeter.  

Onboard USB interface, you can easily charge your digital products. (Note: The USB output voltage is the same as the module output voltage, not a fixed 5V output. Please confirm before charging the USB device)  

High power, high efficiency, 5A, low ripple.

It has two modes of constant voltage and constant current, with indicator light to indicate which mode the module is in.

When used as a lithium battery charger, you can set the floating charging voltage and charging current. Indicates whether it is charging or fully charged. 

With current limiting protection function, even if the output is short-circuited, the module will not be damaged.

The onboard voltage and ammeter can be self-calibrated, which avoids the inaccurate reading of the voltmeter! 

Three major functions:

(1) Used as a common step-down module with overcurrent protection capability;

(2) Used as a charger for lithium batteries, batteries, nickel-cadmium-nickel-metal hydride batteries (battery packs) of various voltage values, for solar panels, wind generators, etc.

(3) Used as a high-power LED constant current drive module. 

Precautions:

The input ground and output ground of the module should not be shared together. This will cause the module's current sampling resistor to bypass, which will make the module unable to adjust the output current. It is easy to burn the module when it is connected to the load.

The output terminal of the module is connected with a current sampling resistor. After connecting the load, there will be a voltage drop of 0 ~ 0.2V, which is normal.

Some customers report that the module output voltage cannot be adjusted. When you encounter this problem, please rotate the potentiometer counterclockwise more than 10 times before using the module to adjust the voltage normally. Because when the module leaves the factory, the default output voltage is 17V.

When the output exceeds 3A and 35W, please strengthen the heat dissipation!
