Timloon Wireless Indoor-Outdoor Thermometer with 3 Remote Sensors — 500ft Range, Temp & Humidity Monitor

Keep precise environmental data for your home, greenhouse, nursery, wine cellar or office with a single kit that reports both indoor and outdoor conditions. The Timloon system includes a tabletop base station plus three wireless transmitters that update every 90 seconds and reach up to 500 feet (150 meters). It shows current values, 24-hour max/min records, comfort level indicators and offers an audible alarm when temperatures exceed your chosen limits.

How accurate are the Timloon sensors and what ranges do they cover?

The three transmitters and the base unit provide reliable consumer-grade readings suitable for everyday monitoring. Indoor readings cover 14°F to 122°F (-10°C to 50°C) and outdoor readings extend from -40°F to 140°F (-40°C to 60°C). Humidity is reported from 20% to 95% with typical accuracy for home use.

• Temperature accuracy: ±1.8°F (±1°C)
• Indoor temperature range: 14°F to 122°F (-10°C to 50°C)
• Outdoor temperature range: -40°F to 140°F (-40°C to 60°C)
• Humidity range: 20%–95% with ±5% typical accuracy

What features help me track changes and set warnings?

The base station records 24-hour maximum and minimum values and displays real-time trend indicators to show whether conditions are rising, falling or steady. You can program individual high/low temperature alarms for the base unit and any of the three remotes; when a threshold is crossed the device sounds an alert. The screen also supports a 20-second backlight for low-light viewing and a low-battery icon for proactive maintenance.

• 24-hour max/min temperature and humidity logging
• Custom high/low temperature alerts per sensor
• Trend arrows for immediate direction of change
• Switchable °C/°F and 20-second backlight

How do the sensors communicate and where can I place them?

Timloon uses a 433 MHz wireless link that updates measurements roughly every 90 seconds, with a line-of-sight range up to 500 feet (150 meters). Each sensor is compact and versatile: mount it on a wall, place it on a tabletop, or attach it magnetically to a refrigerator. Batteries power both the base and remotes so placement is flexible without wiring.

• Wireless range up to 500 ft / 150 m (line-of-sight)
• Update interval: approximately every 90 seconds
• Mounting: wall hang, tabletop, or magnetic attachment
• Power: base uses 3x AAA, each remote uses 2x AAA (batteries not included)

What practical uses does this monitor support around the home?

The multi-sensor configuration lets you watch distinct zones at once — for example, bedroom climate, garage temperatures, greenhouse humidity and an outdoor thermometer near a patio. It’s useful wherever maintaining a stable environment matters but you don’t need professional instrumentation. The comfort indicator simplifies interpretation into wet, comfortable or dry ranges based on humidity and temperature.

• Monitor nursery, bedroom, wine cellar, basement, greenhouse
• Track seasonal swings and appliance or HVAC performance
• Use alarm thresholds for plant protection or pet areas

Who is this for? Timloon’s wireless thermometer kit is aimed at homeowners, hobby gardeners, and anyone who needs multi-point environmental awareness without complicated setup. If you want easy-to-read live data, 24-hour history, configurable alarms and flexible sensor placement across multiple indoor and outdoor locations, this product delivers practical monitoring for everyday needs.
