I bought a Wavetek 1045 RF power meter off eBay a few weeks ago. In this tutorial, I’ll show you how to build three different capacitance meters using an Arduino and a couple. Each capacitance meter has an RC circuit with known resistor values and an unknown capacitor value. One of the most useful things you can do with an Arduino is use it to control higher voltage electronic devices. RF Power of Radio / Base Station) working in 100Mhz to 1800MHz. Then the efficiency of the PA is 67% (RF output power 600mW divided by input DC supply power 900mW). LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0. 2: Block Diagram of Arduino based Watt Meter. The housing is a cheap TEKO box, I bought during last years visit to the HAM RADIO fair in Friedrichshafen. We are also an Arduino, MG chemical, Hammond enclosures, Velleman electronic kits reseller. Note: Meters are NOT supplied in the kit. Calculating your estimated (Calculation for exact will be later) house 3phases's : Power, Energy, PF in Arduino REAL TIME CODE. When the Arduino controller gets power,you will see the blue LED on board is on. Although you might consider the IC as slightly expensive at about $10 in single quantities, its cost is justified by the wide dynamic range and outstanding accuracy offered. Single Chip Very Low Power RF Transceiver Applications • Very low power UHF wireless data transmitters and receivers • •315 / 433 / 868 and 915 MHz ISM/SRD band systems • RKE – Two-way Remote Keyless Entry • Home automation • Wireless alarm and security systems AMR – Automatic Meter Reading • Low power telemetry. I happen to have some Picaxe 08M 8pin pics laying around and decided to do something with them. You can make your own pickups for HF, VHF, UHF and higher. His device has three. Calculating Power 3600 seconds per hour = 3600J per pulse i. I'm learning some basic home automation stuff with Arduino and Raspberry Pi, and I decided to try out some ways to do things wirelessly. When I first started working on my Arduino drone, I decided I wanted to evaluate, understand and compare components before selecting them.
