Frequently Asked Questions

Q: How far can the wireless sensor transmit to the main unit?

A: The Urageuxy WS0403 uses a 433MHz wireless frequency with a transmission range of up to 100 metres (300 feet) in open conditions. Walls and obstacles may reduce range slightly, but it is designed to perform reliably through standard home construction materials, including for basement or garden use.

Q: How many sensors can I connect to the main unit?

A: The main display unit supports up to 8 wireless sensors simultaneously. Only 1 sensor is included in the box, but additional compatible sensors can be purchased separately, making it ideal for monitoring multiple rooms, a baby nursery, a greenhouse, and an outdoor area all at once.

Q: Does the thermometer hygrometer require batteries, and what type?

A: Yes — the main display unit requires 2× AAA batteries and the remote sensor requires lithium batteries. Neither are included in the package. Using lithium batteries in the sensor is especially recommended for outdoor or cold-environment use, as they maintain stable performance at low temperatures.

Q: Can this unit be mounted on a wall or does it only stand on a desk?

A: The WS0403 is designed for both wall mounting and freestanding use. Wall-mounting accessories and a user manual are included in the box, so you can place it wherever it's most convenient — on a desk, shelf, or fixed to a wall in your office, baby room, or living space.
