📡 The digital sentinel that monitors every percentage point of humidity.
When the sensor is faulty, the control unit no longer detects humidity correctly, causing disastrous hatching due to dehydration or drowning of the embryos.
Quick diagnosis: Display showing incorrect values (stuck at 0% or 99%), humidity not responding to real changes, unstable readings that constantly jump. It's often thought to be the control unit, but the culprit is actually the sensor.
Solution: Original FIEM SHT31 humidity sensor complete with circuit board and protective case. Accuracy ±2%, fast response. Lifespan: 5–7 years in normal use.

📌 Real case: Bologna breeder with INCA, sensor stuck at 45%. Actual humidity was 70%, chicks drowned in their shells. Sensor replaced, readings accurate, and hatchability returned to 85%.
⚠️ When to replace it: at the first signs of incorrect readings. Waiting means losing entire broods due to incorrect parameters.
