TempPro TX-2B Outdoor Humidity Sensor for 915MHz Indoor/Outdoor Thermometers

Enhance your weather monitoring with the TempPro TX-2B outdoor sensor

The TempPro TX-2B outdoor sensor is designed to pair with compatible 915MHz TempPro base units (TP60, TP62B, TP65B, TP63B, TP200B). This is an accessory and cannot operate on its own. If your current base unit matches one of these models, you can extend your monitoring to a dedicated outdoor channel with real-time temperature and humidity readings feeding back to your base unit.

Key capabilities at a glance

• 500 ft (150 m) remote range to transmit conditions back to your base unit
• Outdoor temperature range from -58°F to 158°F (-50°C to 70°C) with about ±2°F accuracy
• Humidity readings from 10% to 99% RH with approximately ±2–3% RH accuracy
• Monitor up to four locations by adding additional sensors; initial channel is 1, with channels 1–3 selectable on the back
• Tabletop or wall-mount design for flexible placement; includes 2 AAA batteries for immediate setup
• TempPro continues the ThermoPro mission under a new name; you may receive either brand in shipment

What you get

• Outdoor wireless sensor module
• Two AAA batteries for quick use
• Simple installation guide to start monitoring

Usage tips and best practices

• Place the sensor in a shaded, open area away from direct sun or heat sources for more stable readings
• Use the back slider to assign channels (1, 2, or 3) when you add multiple sensors to your system

With the TX-2B, you can broaden your monitoring footprint—great for greenhouses, sheds, or other outdoor spaces—while keeping readings centralized on your existing TempPro base unit. While results can vary with environmental factors, the sensor is built to provide consistent, real-time data to help you gauge conditions at a glance.
