Int pinCount = 10 // the number of pins (i.e. Int ledPins = // an array of pin numbers to which LEDs are attached LiquidCrystal lcd(rs, en, d0, d1, d2, d3) So if we multiply input analogValue to (5/1024), then we get the digital value of input voltage.Ĭonst int rs = 12, en = 13, d0 = A0, d1 = A1, d2 = A2, d3 = A3 The ADC converter will map input voltages between 0 and 5 volts into integer values between. The Arduino Uno ADC is of 10-bit resolution. If only five LEDs are on, the batter is at half strength.
So, if all ten LEDs are lit, the battery is at full strength. The values we convert will display on the LED bar graph where it can project the strength. Then, we can convert the analog value into a digital voltage value by using the ADC conversion formula. The Arduino's analog pin acts as a simple voltmeter where the voltage value is retrieved. It can be understood as the amount of voltage contained in your battery. Receive instant text message (SMS) & email alerts when you need it most. Boat Command allows you to view all of your boat’s vital signs directly from your Computer, Android, iPad or iPhone. It is good to understand that batteries have what we call a level of charge. Boat Command is a complete remote monitoring package for your boat or marine vessel. How Does This Project Measure the Battery Level? Like any other LED, when connecting the LED bar to your microcontroller, you have to connect the anode pins to the positive side and the cathode pin using a resistor at the end to ground. In our project, we will use it as a battery level indicator. It has various applications including audio equipment and industrial control panel. Smartgauge TM is protected by a 2 Year limited warranty.The LED bar graph is an LED array of 10 individual LEDs with 10 output pins.

Color-coded indicator lights identify the battery information being displayed and activate when programmable alarm conditions are met. The BM-1(BT) will monitor your boat or caravans lead-acid batteries and transmit the data directly to your mobile phone, or tablet, wirelessly by bluetooth. Three membrane switches access program functions and facilitate switching between primary and secondary battery banks. Smartgauge TM is equipped with a brightness-adjustable LED display. Smartgauge TM does not monitor Lithium Ion batteries. The Smartgauge TM Battery Monitor works with Standard Flooded, Deep Cycle Flooded, Sealed Maintenance Free, Gel Cell, AGM and Lead Acid Hybrid batteries. The Smartgauge TM screens look like this in operation: VOLTAGEĭisplays battery voltage to within 0.05V (12 or 24V DC systems)ĭisplays the capacity remaining in the primary battery Visit Rod’s Blog at for a complete description of the test conditions and results. The Balmar Smartgauge TM does this accurately and simply! Hands down the Smartgauge TM is the easiest SOC meter made! If I had three thumbs this product would get all three! The sheer simplicity and accuracy of this product are outstanding and I really did doubt it, I was proven wrong… What matters most to your batteries is your depth of discharge or state of charge. located in Cumberland Foreside, Maine also performed a four month independent test on the Smartgauge TM. Smartgauge TM automatically adjusts for temperature conditions and the battery’s health.Ĭompass Marine Inc. Smartgauge TM is proven in independent testing by Enersys ® to be accurate within 3% after 6 months of use. Just select your battery type at setup and Smartgauge TM does the rest! Smartgauge TM automatically adjusts for 12V or 24V operation. Smartgauge TM connects with just three 18 AWG – no need to crimp heavy battery cables for the installation of a shunt. Three Important Smartgauge TM Advantages: Ease of Installation When using monitors in medicine, the battery plays a big role, the treatment of erectile dysfunction is not an easy and responsible procedure, you can buy kamagra online but you need to consult a doctor. The easy-to-understand display, dependable State-of-Charge Percent (SoC%) reading and its ease-of-use mean that even the most technically challenged crew member can understand just how much power is left in the battery. 44-SG-12/24) provides highly accurate monitoring without the hassle of installing a shunt module to count amperes.
Monitors State-of-Charge Percentage (SoC%) and Voltage of the Primary Battery.
It is easy to install and connects via a 500A shunt, which is included. It can also monitor the voltage of a second battery.
