It's an ankle monitor that detects whether or not you've consumed alcohol:

Secure Continuous Remote Alcohol Monitor, records the wearer's alcohol intake by measuring air and perspiration emissions from the skin every hour. It detects blood alcohol levels as low as 0.02 percent, which corresponds to one drink or less an hour, and can even tell when the alcohol was consumed.
