Product Description The FY-12 Mini Digital LCD Thermometer and Hygrometer is a high-precision, ultra-compact environmental monitoring device designed for real-time tracking of temperature and humidity levels. It features a clear, easy-to-read LCD screen that simultaneously displays both metrics, making it ideal for specialized environments such as egg incubators, reptile terrariums, cigar humidors, and 3D printer filament storage boxes. The module is designed for panel mounting with a snap-in structure, allowing it to be seamlessly integrated into custom enclosures or dashboards. Its low power consumption and battery-operated design ensure long-term continuous monitoring without the need for external wiring.

Key Features

  • Dual Monitoring: Provides simultaneous digital readings of ambient temperature and relative humidity.

  • Compact Snap-in Design: Small footprint with a built-in flange for easy mounting into rectangular panel cutouts.

  • Wide Measurement Range: Capable of measuring sub-zero temperatures and high-humidity environments with high stability.

  • Battery Powered: Operates on two standard LR44 button cells, offering months of operation before requiring a replacement.

  • Large Clear LCD: Optimized for high-contrast visibility,

Technical Details

  • Sensor Type: Utilizes an integrated thermistor for temperature and a capacitive polymer humidity sensor for moisture detection.

  • Refresh Rate: Updates the LCD every 10 seconds to provide a consistent balance between real-time data and battery longevity.

  • Temperature Resolution: Provides precise readings down to 0.1°C, essential for delicate incubation processes.

  • Humidity Resolution: Displays relative humidity in increments of 1% RH across the entire 10% to 99% spectrum.

  • Accuracy Calibration: Factory calibrated to maintain a tolerance of ±1°C for temperature and ±5% for humidity.

  • Power Management: Highly efficient CMOS circuitry draws minimal current, maximizing the life of the 1.5V AG13/LR44 batteries.

  • Operating Environment: Designed to function reliably in non-condensing environments between -50°C and 70°C.

  • Housing Material: Built from industrial-grade ABS plastic for impact resistance and durability in humid conditions.

  • Display Units: Standard Celsius (°C) readout; the high-contrast segments are visible in diverse lighting environments.

  • Installation Style: Features side-mounted clips that secure the unit into a 45mm x 26mm rectangular cutout.

  • Portability: Lightweight at only 25g, making it suitable for portable flight cases and travel-sensitive equipment.

  • Ventilation Ports: Strategically placed openings on the rear allow for natural airflow to reach the internal sensors for accurate readings.

  • Visual Clarity: Features an LCD glass designed to minimize glare and reflection.

  • Maintenance: Tool-less battery replacement via a slide-out compartment on the back of the unit.

  • Compatibility: Completely standalone device; requires no external microcontroller or programming to function.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: This device is standalone and runs on 1.5V button cells. Do not attempt to power it with a 9V battery, as the internal logic will be destroyed instantly.

  • 18650 Cell: If you wish to build a long-term logging station using an 18650 cell, you must use a buck converter or LM317 IC to drop the voltage down to 3V (to simulate 2x LR44 batteries in series).

  • IC & Capacitor Tip: If you are integrating the sensor readout into a data-logging system with an ESP32, consider using a DHT22 IC instead. If you find the LCD fading, add a 10uF electrolytic capacitor across the battery terminals to stabilize power delivery as the button cells age.

  • Related Products: We recommend pairing this with our Waterproof DS18B20 Temp Sensors, 3D Printer Dry Boxes, and Reptile Heating Pads.
