Wi-Fi Temperature Controller, app control, cloud logging

Product Description:

This smart thermostat module offers precise local and remote temperature control with advanced features packed into a compact form. It accepts 6–30V DC input and includes a waterproof NTC10K thermistor probe. It also supports digital DS18B20 sensors via a separate connector, auto-switching between sensor types when detected.

The thermostat can operate in heating or cooling mode, with adjustable setpoint and hysteresis. It includes a high/low temperature alarm, configurable delay timer, and calibration offset. The onboard LCD screen displays the current temperature, mode status, and setpoints. All settings can be adjusted with the three onboard buttons.

For remote control, the module connects to 2.4 GHz WiFi and integrates with the Sinilink mobile app (Android and iOS). The app allows you to change settings, switch modes, toggle the relay, and view historical temperature logs with up to 15 days of cloud data. Notifications for high and low temperatures can be configured directly in the app.

An onboard 10A relay provides dry-contact switching for AC or DC loads such as heaters, fans, compressors, or alarms.

Main features:

• Operating voltage: 6–30V DC
• Control range: -40°C to +110°C
• Temperature accuracy: 0.1°C resolution
• Relay output: dry contact, 10A max at 30V DC or 250V AC
• Sensor support: NTC10K (included), DS18B20 (optional)
• LCD display with 3-button interface
• Heating or cooling mode selectable
• Adjustable hysteresis (temperature difference)
• High and low temperature alarms (buzzer and app notification)
• Relay start delay timer (protects compressors or devices from short-cycling)
• Temperature calibration offset
• Memory for all settings after power loss
• WiFi connectivity with Sinilink app for remote control and monitoring
• 15-day cloud data logging with real-time trend charts
• Optional emergency stop via app

Use cases include incubators, greenhouse climate control, aquariums, HVAC regulation, smart home brewing, fermentation, or any application that needs accurate and remotely accessible thermal management.
