A solar controller or solar regulator is similar to the voltage regulator in your car. It regulates the voltage and current coming from the solar panels going to the battery. Most “12 volts” panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged. Generally, there is no need for a Solar Controller with the small maintenance, or trickle charge panels, such as the 1 to 5-watt solar panels. A rough rule is that if the panel puts out about 2 watts or less for each 50 battery amp-hours, then you don’t need one. For example, a standard flooded golf car battery is around 210 amp-hours. So to keep up a series pair of them (12 volts) just for maintenance or storage, you would want a panel that is around 4.2 watts. The popular 5-watt panels are close enough, and will not need a controller. If you are maintaining AGM deep cycle batteries, such as the Concorde Sun Xtender then you can use a smaller 2 to 2-watt panel. This Solar Panel Charger Controller Regulator is specially designed to protect the battery, which is able to keep the battery on full voltage condition and prevent the battery from overcharging, over-discharging and supplying power to solar panels during nights.   Features Microcontroller digital accuracy PWM charge mode & State of Charge(SOC) Fully automatic operation & Electronic protections Detects day and night using the PV array, timer setting Double digital LED display, numbers equal to timer setting Temperature compensation, with inside temperature sensor Big terminals, big distance between terminals Light & Timer Control 12V / 24V Auto Intelligence Backplate cooling design   Protection Overcharging protection Can be used for all panels Over-discharging protection Short and Open Circuit protection Full specification available if required Fail Safe and cannot be damaged by accidental wiring mistakes Advanced design with simple plug and play technology.

This is a 10 degree of freedom device which incorporates a MPU6050 accelerometer and gyro chip, a HMC5883L digital compass, and a BMP180 barometer. These are all common chips and there is plenty of code around for each of them.   The MPU6050 devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon 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. The devices are offered in the same 4x4x0.9 mm QFN footprint and pinout as the current MPU-3000? family of integrated 3-axis gyroscopes, providing a simple upgrade path and making it easy to fit on space constrained boards. The InvenSense Motion Apps Platform that comes with the MPU-6050 abstracts motion-based complexities, offloads sensor management from the operating system and provides a structured set of APIs for application development. 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. The HMC5883 is a surface mount multi-chip module designed for low field magnetic sensing with a digital interface for applications such as low cost compassing and magnetometry. The HMC5883 includes our state of the art, high-resolution HMC118X series magneto-resistive sensors plus Honeywell developed ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, 12-bit ADC that enables 1° to 2°compass heading accuracy. Applications for the HMC5883 include Mobile Phones, Netbooks, Consumer Electronics, Auto Navigation Systems, and Personal Navigation Devices. The BMP180 is the new digital barometric pressure sensor of Bosch Sensortec, with a very high performance, which enables applications in advanced mobile devices, such as smart phones, tablet PCs and sports devices. It follows the BMP085 and brings many improvements, like the smaller size and the expansion of digital interfaces.The ultra-low power consumption down to 3 ?A makes the BMP180 the leader in power saving for your mobile devices. BMP180 is also distinguished by its very stable behavior (performance) with regard to the independency of the supply voltage.   Applications FPV, RC and Robots systems GPS navigation systems Impact recognition and logging Gaming and virtual reality input devices Motion-activated functions Intelligent power saving for handheld devices Vibration monitoring and compensation Free-fall detection 6D-orientation detection   Features Acceleration, Gyroscope and Magnetometer 10DOF modules (three-axis gyroscope + triaxial accelerometer and three-axis magnetic field + atmospheric pressure) Build in ultra low noise linear LDO voltage regulator Build-in on board filters, which reduce noise from motor and other high current electronics All sensors connected to I2C bus Build in Logic level converter for I2C Power indicator LED   Specifications Power Supply: DC3.3V-5V Communication: IIC protocol (fully compatible with 3-5V system containing LLC circuit) Chips: MPU6050 + HMC5883 + BMP180 Size: 2.2cmx1.7cm Weight: 6g   FAQ What is Degrees of Freedom (DOF), see here
