This circuit is designed to monitor the atmospheric charge. By observing the increase in the atmospheric charge, it is possible to predict a nearby lightning. The sudden electric discharge during a lightning may cause the flow of excessive current to earth which may be detrimental to the appliances connected to mains lines.
3 Volt Lithium Cells are extensively used in low power applications such as Digital clocks, Toys etc. These are also used in Computer Mother boards as backup power source to keep the memory. The circuit described here is a handy tester to check the voltage level in the used Lithium cell before throwing it away.Even if it carries less than 2 volts, it can be used again in some very low power applications that require less than two volts. The circuit uses an LED as a Zener diode to give 2.2 V reference voltage to compare the voltage level in the Lithium cell.
This circuit tells you that whether your body is relaxed or not. It exploits the skin’s galvanic property to measure the stress level of the body. Even though the circuit do not measures the stress level precisely, it can be used as an indicator to know the stress level.
Here is a circuit that can sense the static electricity level in the atmosphere. It gives LED indications for both positive and negative atmosphere charges.
