Three-sensor monitoring

The OBET B63-HEI wireless thermometer ships with three remote sensors and a base unit that displays temperature and humidity for up to three separate locations. Signal reach extends to 500 feet, making it practical for a home, office, garden, garage or RV where multiple zones need watching at once.

USB backlight and power flexibility

When the base unit is connected via the supplied USB cable the backlight stays on continuously with three brightness levels; on battery power the display shuts off after ten seconds to conserve energy. The package includes the base unit, three sensors, one USB cable and an instruction sheet, so no extra accessories are required to start monitoring.

Check sensor placement and battery type

Verify that each sensor can be positioned within the 500-foot open-air range of the base unit and that the intended mounting spots fall within the outdoor temperature span of -50 to 158 degrees Fahrenheit. The base unit runs on three AAA batteries when not plugged into USB, and those batteries are not included in the box.

Questions about this item

How often do the three sensors and base unit need fresh batteries when running on battery power?

Each sensor and the base unit take standard AAA cells; the display blanks after 10 seconds on battery to extend life, so replacement frequency depends on how often you wake the screen.

At what point does the wireless link to the sensors become unreliable?

The system is rated for up to 500 ft line-of-sight; walls, metal cladding or heavy foliage will reduce that distance and may cause drop-outs first.

Does the base unit get warm or draw noticeable power when the backlight stays on via USB all day?

With USB connected the backlight can run continuously at high, low or off; the unit draws only the modest current needed for the display and receiver, so heat is minimal.
