2PCS Digital Thermostat Controller -58F to 230F Programmable Heating Cooling Switch 12V DC with Waterproof NTC Sensor Dual Color LED Display for HVAC Aquarium

Precision Temperature Control, Automatically. Take the guesswork out of temperature management. Our advanced Temperature Monitoring Controller automatically switches connected devices on or off based on your exact settings. When the temperature rises above or falls below your chosen threshold, the relay activates—lights on, equipment running. When the target temperature is stable, it disconnects—lights off, energy saved. It’s the smart, hands-free solution for a wide range of applications. Key Features & Technical Excellence Experience unparalleled control with high-precision components. The 10K 0.5% NTC temperature sensor delivers accurate readings from a wide -50°C to 110°C (-58°F to 230°F) range. With an elaboration precision of ±0.1°C and a rapid refresh rate of 0.5 seconds, you get real-time, reliable data for immediate response. Versatile Application Scenes Imagine the possibilities: Maintain the perfect temperature in your homebrew fermentation tank, protect sensitive electronics from overheating in an enclosure, automate a reptile terrarium's heat lamp, or manage a greenhouse fan. This controller brings intelligent automation to your hobbies and projects, ensuring optimal conditions around the clock. Reliable Performance & Safety Built for durability and safety, the controller handles compatible loads up to 5A/15A 220VAC or 20A 14VDC. The built-in high-temperature protection (0-110°C) offers an extra layer of security for your equipment. With low power consumption (≤35mA static), it's an efficient addition to any 12V DC system.
