ACme: Berkeley Wireless AC Meter/Switch

Purpose

ACme is an open source hardware and software platform that enables wireless energy/power measurement and control of AC devices. The ACme node (pictured on the left) fills the gap between inexpensive LCD watt-meters (e.g. Kill-A-Watt) and expensive networked enterprise energy monitors. The ACme network (pictured on the right) is an IPv6 based mesh network that enables direct IP communication with individual ACme nodes.

Energy Management Architecture

Purpose

1. Enables graceful degradation and run-time adaptation of the sensornet, by allowing prioritized specification of user requirements.
2. Allows the end user to declaratively express his/her requirements, such as sampling rate and lifetime.

SPOT - Scalable Power Observation Tool

Purpose

SPOT enables in situ measurement of nodal power and energy over a dynamic range exceeding four decades or a temporal resolution of microseconds. Using SPOT, every node in a sensor network can be instrumented, providing unparalleled visibility into the dynamic power profile of applications and systems.

Ultrasonic Transceiver

Purpose

The ultrasonic transceiver board is developed to measure distances between motes (ultrasonic ranging). The ultrasound transducer is connected to an Atmel Atmega8 microprocessor, which coordinates between RF signals and ultrasound signals to perform time-of-flight ranging.
