And Indoor/Outdoor Temperatures 
Monitor environmental conditions indoors and out from the comfort of your home or office with the new Cable Free™ Thermohygrometer. Using wireless, weatherproof remote sensors, it can monitor and display temperature and relative humidity at up to three locations in and around your home or business from a distance of up to 100 feet. A total of three remote sensors can be used and they are "channel selectable" from the display.
The desktop/wall-mountable indoor display unit with jumbo LCD screen also has an internal sensor to show room temperature. And it measures relative humidity from a range of 25% to 95% and shows reminder icons for comfort/wet/dry.
The remote sensors use radio-frequency transmissions at 433 MHz and have their own LCD screen for temperature and humidity display. Use them in the garden or greenhouse, baby's room, wine cellar or basement, factory floor, and elsewhere.
Additional remote wireless sensors are available here.
One wireless remote sensor is included; extras are an optional purchase. Displays temperature/humidity trend as well as memorizes hi/low conditions. Main unit uses 2 AA batteries and sensors use 2 AA batteries; all batteries are included.
