ELECTRIC POWER-CONSUMPTION MONITOR x POWER-CONSUMPTION MONITOR (ELECTRIC) xx ELECTRIC xx METER (ELECTRONIC) xx VOLTAGE MONITOR xx WATTMETER A simple running-time meter. Convert a battery-powered quartz alarm clock into an inexpensive 12-hour meter to log how long an electrical device is operated. How to understand and keep tabs on your electric bill. Tips on checking the bill, reading the meter and charges for extra services. How to read home gas and electric meters and how to compute the amount of energy consumed during any given period. POWER, a program written in North Star BASIC which will help analyze your usage of electrical power. The program calculates the cost per month and per hour of operating specific electrical appliances, based on their electrical specifications (amperage and voltage). Electrical-energy measurement with the Apple II. Hardware and software to perform data-logging functions on a wind-driven generator or bank of solar cells. Build the AC power monitor. Use your computer to measure electrical power consumption. Handles from 30 to 1800 Watts of 120 volt AC current. Energy consumption monitor can display the accumulated cost (in cents) for any home appliance connected to the monitor. Can also be used as a power meter by connecting a DMM and interpreting the output voltage as wattage. Est. cost: $60 (kit). Simple circuit to estimate the power consumed by a 120-volt AC appliance. Ultra-simple and inexpensive elapsed time meter can be used to measure how long electrical devices are drawing current. Built around a 555-type IC. Energy sentry. Ten LED's give an indication of the power consumption of any appliance drawing up to 1500 watts. Estimated cost: $25. On-time recorder measures the amount of time that current flows through an electric-power cord. Understanding how to read your electric meter and electric bill. The Energy Saver program. A BASIC program which will calculate the electric operating cost for a number of devices found around a home. Electric bill watchdog. A BASIC program which will figure your electric bill and help conserve energy by forcasting your next bill and your annual cost. Electric bill computer program analyzes your electric consumption month by month. Written in basic for a PET computer. All-purpose appliance tester measures actual operating power comsumption. Two energy-related programs. (1) Computes the miles per gallon you can get on your automobile. (2) Computes the average cost of each kilowatt-hour of electricity. Written in BASIC. Energy auditor. A digital electronic device to keep tabs on the amount of electricity any appliance uses. May be used with appliances such as water heaters, air conditioners, etc. which draw large amounts of current. Est. cost: $40. The Watt Watcher. Inductive-pickup meter monitors AC power usage so that you can manage energy consumption. Displays actual power usage in kilowatts from moment-to-moment without ambiguity. Any change in the load immediately registers on the meter. Less electricity, same good life. How to assess an appliances consumption of electricity and modify their usage to reduce electric bills. How to read an electric meter. Build the time-on recorder. Tells you at a glance how long an appliance or TV receiver has been operating. Power meter keeps track of how much electricity an appliance uses. Handles appliances between 15 and 1100 watts. Build an in-line AC wattmeter to show the power consumption of your major appliances. Heater monitor will light an LED whenever a heat cable (or some other AC electrical device) is drawing current. Circuit for an energy-use monitor. Use it to clock how long a particular appliance operates. Then you can calculate how much electricity it has consumed. Energy consumption monitor. Find out how much it costs to run your household applicances. Can also be used as a power meter by connecting a DMM to the voltage output of the monitor. Est. cost: $60 (kit). How to install and use energy cost indicators (power monitors) which continuously display the cost of electrical power being consumed (at the current rate). Home energy sentry uses ten LED's to indicate if the appliance being operated costs 1,2,...10-cents per hour to operate. Will handle appliances up to 1500 watts. A look at the energy consumption of power tools. How to reduce your electric bill by managing electric energy demand. | |||||||||
