XM-18 Digital Automatic Small Egg Incubator Thermostat Controller with Temperature and Humidity Sensor

The XM-18 is a precision digital thermostat controller specifically engineered for small-scale egg incubation systems, featuring integrated temperature and humidity sensing with real-time LCD display feedback. Professional poultry farmers, hatchery operators, and agricultural research institutions rely on this controller to maintain the critical environmental parameters required for optimal embryonic development and hatch rates. This device solves the critical problem of manual temperature and humidity monitoring by providing automated control with high-accuracy sensors, eliminating human error and significantly improving hatchability percentages in commercial and hobbyist incubation operations.

Product Overview

The XM-18 Digital Automatic Small Egg Incubator Thermostat Controller operates on a closed-loop PID control algorithm that continuously monitors ambient conditions through its integrated DHT temperature and humidity sensor, then automatically adjusts heating elements to maintain setpoint temperatures within plus-minus 0.5 degrees Celsius accuracy. The device features a dual-relay output configuration allowing independent control of heating and cooling circuits, essential for maintaining the precise 37.5 degrees Celsius (99.5 degrees Fahrenheit) required for chicken egg incubation or alternative temperature profiles for other poultry species including duck, quail, and turkey eggs.

This model distinguishes itself through its compact form factor optimized for small incubators ranging from 48 to 200 egg capacity, 12V DC power supply compatibility for both grid and solar-powered installations, and a user-friendly interface with four-button navigation and 16x2 character LCD display. The controller includes programmable hysteresis settings, adjustable sensor calibration, and humidity alarm thresholds, making it suitable for both manual-turn and automatic-turn incubator systems. Built-in over-temperature protection with audible alarm prevents catastrophic embryo loss from heating element failures.

• Educational institutions and veterinary colleges demonstrating embryology and incubation principles with hands-on laboratory equipment

How to Use

Begin by mounting the XM-18 controller in a weatherproof electrical enclosure adjacent to your incubator, ensuring the DHT22 sensor probe is positioned in the center of the incubator chamber away from direct heating elements, approximately 2 to 3 inches below the eggs. Connect the 12V DC power supply to the controller terminals, then wire your heating element to the heating relay output terminals and any cooling fan or ventilation system to the cooling relay output terminals. Power on the device and use the four navigation buttons to access the menu system, setting your desired temperature setpoint typically 37.5 degrees Celsius for chicken eggs and humidity alarm range between 40 to 70 percent relative humidity.

During the initial 24-hour calibration period, compare the displayed temperature reading against a calibrated mercury thermometer or digital reference instrument placed at the sensor location. If discrepancy exceeds plus-minus 0.5 degrees Celsius, access the calibration menu and adjust the offset value accordingly. Monitor the LCD display continuously during the first week of incubation, observing that the heating relay engages when temperature drops 0.3 degrees below setpoint and disengages when reaching setpoint, indicating proper PID control operation. Check humidity readings twice daily with a separate hygrometer to verify sensor accuracy, and clean the DHT22 sensor probe monthly using a soft dry cloth to maintain measurement precision throughout the 21-day incubation cycle.

Frequently Asked Questions

What is the temperature accuracy of the XM-18 controller and how does it maintain setpoint during incubation?

The XM-18 achieves plus-minus 0.5 degrees Celsius accuracy using a DHT22 temperature sensor with 16-bit resolution and a closed-loop PID control algorithm. The controller continuously samples the sensor every 2 seconds, calculates the deviation from your setpoint, and adjusts the heating relay duty cycle proportionally to minimize temperature oscillation. This prevents the thermal shock that causes embryo mortality and ensures consistent incubation conditions throughout the 21-day cycle.

Can the XM-18 be used with both forced-air and still-air incubators?

Yes, the XM-18 is compatible with both incubator types. For forced-air incubators, the sensor should be positioned at egg level in the center of the chamber. For still-air incubators, position the sensor 2 to 3 inches above the eggs to account for natural temperature stratification. The controller's dual-relay output allows you to control a circulation fan independently from the heating element, making it suitable for either configuration.

What happens if the sensor fails or becomes disconnected during incubation?

The XM-18 includes sensor failure detection that triggers an audible alarm and halts all relay outputs when the DHT22 sensor connection is lost or reading becomes impossible. This fail-safe design prevents uncontrolled heating that would damage embryos. Immediately check the sensor connection and wiring, clean the sensor probe if necessary, and verify the connection is secure. The device will resume normal operation once sensor communication is restored.

Is the XM-18 suitable for incubating duck or quail eggs with different temperature requirements?

Yes, the XM-18 supports multiple species by allowing you to program different setpoint temperatures. Duck eggs require 37 degrees Celsius compared to 37.5 degrees Celsius for chicken eggs, while quail eggs require 37.8 degrees Celsius. Simply adjust the setpoint value in the controller menu to match your target species. The humidity requirements also vary by species, so configure the humidity alarm thresholds accordingly for optimal hatch rates.
