Home Made Circuits and Schematics

This is the circuit diagram of a simple corrosion free water level indicator for home and industries. In fact the the level of any conductive non corrosive liquids can be measured using this circuit. The circuit is based on 5 transistor switches. Here is a simple, versatile project which indicates the level of water and automatically controls it by using PIC Microcontroller Controller module requires +5v and +12v supply. Circuit Diagram: Level Sensor module is made of with HT12E encoder A wireless water-level indicator using microcontroller (MCU) is costly and not very easy to program. Presented here is a low-cost wireless water-level indicator without an MCU full and overflow. Circuit diagram of the transmitter unit is shown in Check out the new water level sensor circuit. The simple water level We are sorry for the poor quality of the water level indicator schematic quality. If you have higher quality pictures of this water level diagram use the discussion form below. This water-level indicator Assemble the circuit on a general-purpose PCB and enclose in a suitable box. Use a non-corrosive material such as steel strip for the five sensors and hang them in the water tank as shown in the circuit diagram. In this projects, i will show you how to make a Battery Level Indicator. I got this idea because i need this tools for indicate my powerbank battery level, so i made this tools. No more talking, LET'S MAKE IT! If you finish solder your circuits .

The following post describes a simple low battery indicator circuits. As shown in the following circuit diagram, the two transistors are configured as voltage sensor and inverter. The first transistor on the left senses the threshold voltage level I can get you a wiring diagram of the engine and the control but He was concerned about which wires indicate the engine oil level, gas, and I think he said battery charge indicator, plus other marine gauge connections. He was looking for the color Aim: a circuit that lets you know the battery level of a device from the number of LEDs that are This bar graph LED battery level indicator circuit is based on LM3914 monolithic IC from National Semiconductor that senses the voltage levels of the battery Battery level voltage measurement is best done with a dummy load. This circuit has four LEDs to show the charge left. It is important to avoid overcharge or deep discharge of rechargeable batteries. Never try recharging normal batteries. Using rechargeable .
