THR320 Temp & Humidity Monitoring Device

Automate high-capacity climate control in your poultry houses, incubators, and farm facilities with the SONOFF Origin THR320 Smart Temperature and Humidity Monitoring Switch. Upgraded with a massive 20A relay capacity and an updated RJ9 sensor interface, the THR320 allows you to monitor environmental conditions in real time via the eWeLink app, view up to 6 months of historical data, and create custom automated trigger scenes to maintain optimal conditions.

Featuring an internal dry contact output option alongside its high-power mains supply, the THR320 acts as an intelligent smart thermostat and hygrostat—automatically switching heavy heating, cooling, or ventilation equipment on or off when set thresholds are reached to protect your flock's health and performance.

Key Features

• 20A Heavy-Duty Capacity: Handles massive electrical loads up to 20A (4600W), making it ideal for direct, relay-free control of large exhaust fans, wet wall pumps, and high-wattage heating units.

• Real-Time Tracking & Auto Mode: Displays live temperature and humidity readings on your smartphone; configure custom high and low thresholds to automate connected gear hands-free.

• 6-Month Historical Data Logs: Automatically records hourly microclimate data; review or export logs to Excel to track flock growth environment curves and incubator stability.

• Dry Contact Relay Output: Features a potential-free dry contact output to safely trigger low-voltage systems, signal circuits, or external automation contactors.

• Upgraded RJ9 Sensor Port: Secure clip-in RJ9 4P4C connection delivers stable data transmission (compatible with THS01 temp/humidity, WTS01 waterproof temp, and MS01 soil sensors).

• Voice Control & Smart Scenes: Integrates seamlessly with Google Assistant and Amazon Alexa for hands-free status updates and automated scene triggers.

Practical Uses in Poultry Houses & Hatchery Setups

Maintaining precise temperature and relative humidity directly impacts chick survival, feed conversion, and egg hatchability:

• High-Power Space Heating Control: Directly switch heavy-duty indirect air heaters or brooder heater banks without needing external contactors during cold night drops.

• Automated Wet Wall & Evaporative Cooling: Trigger cooling pumps or heavy circulation fan banks when house temperatures exceed target curves to prevent heat stress.

• Incubator & Hatching Room Monitoring: Track humidity and ambient air temperatures with high precision, logging seasonal dips and sending instant phone alerts if readings drift off-target.

• Ammonia & Moisture Exhaust Cycles: Run heavy ventilation fans based on relative humidity triggers to extract excess moisture and keep litter dry.
