We know that every semiconductor electronic component changes its electrical conductivity in response to the varying ambient temperature. The simple incubator circuit presented here is absolutely free from these drawbacks and will produce comparatively high degree of accuracy as far the upper and the lower tripping operations are concerned. However, the transition points between the switching are too long and not consistent and therefore not reliable for accurate operations. The moment it reaches its previous shape, the electricity supply to the heater is restored through its contacts and the cycle repeats. Since the electricity to the heating device passes through this metal, it’s buckling causes the contact to break and thus power to the heating element is interrupted - the heater is switched off and the temperature starts falling.Īs the temperature cools, the bimetal starts straightening to its original form. When the temperature to be sensed reaches the threshold point of this metal, it bends and buckles. Normally these types of temperature sensor or thermostats fundamentally use the ubiquitous bimetal strip for the actual tripping operations. The conventional electromechanical temperature sensors or thermostats are not very efficient due to the simple reason that they cannot be optimized with accurate trip points. Drawbacks of Electromechanical Thermostats This simple electronic incubator thermostat will very faithfully sense and activate the output relay at different set temperature levels from 0 to 110 degree Celsius. Here we discuss a simple construction procedure of an electronic incubator thermostat. Switching a particular load at different threshold temperature levels doesn’t necessarily need complex configurations to be involved in an electronic circuit. The sensing range is quite good from 0 to 110 degrees Celsius. The advantage of artificial incubation is faster and healthier production of the chicks compared to the natural process. Here the temperature is precisely optimized to match the natural incubating temperature level of eggs, which becomes the most crucial part of the whole system. How Incubators WorkĪn Incubator is a system where bird/reptile eggs are hatched through artificial methods by creating a temperature controlled environment. The setting may be completed through two discrete variable resistors. An electronic incubator thermostat circuit shown in this article is not only simple to build but is also easy to set and acquire exact tripping points at various different set temperature levels.
