Digital Thermometer Thermostat

A complete digital thermometer and thermostat controller with an LED temperature display, adjustable set-point, and relay output — turning a heater or cooler on/off automatically to maintain your target temperature. No programming required — set your target temperature on the front panel and it runs autonomously.

🔹 Key Applications

• Temperature-controlled incubator heating
• Greenhouse heater and fan automation
• Aquarium temperature regulation
• Fermentation and brewing temperature control
• 3D printer enclosure temperature management
• Reptile vivarium heating control

🔹 Why Choose This Module?

• All-in-one thermometer + thermostat — no external controller needed
• Relay output — directly switches heaters, fans, and coolers
• NTC probe included — ready to deploy
• Adjustable hysteresis — prevents rapid relay cycling
• LED temperature display — always-visible readout

🔹 Technical Specifications

• Temperature Range: -50°C to +110°C
• Probe: NTC (included)
• Output: Relay (10 A)
• Set-Point: Adjustable via front panel
• Hysteresis: Adjustable
• Operating Voltage: 12 V DC

🔹 What's Included

1 × Digital Thermometer Thermostat Controller with NTC Probe

🔹 Pro Tip

💡 Set the hysteresis (differential) to 1–2°C to prevent relay chattering when temperature hovers near the set-point. For heating applications, the relay energises when temperature drops below (set-point − hysteresis) and de-energises when it reaches the set-point. Wire the heater through the relay NO contacts.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
