Unit NCIR is a single‑point infrared temperature measurement sensor. It features a built‑in infrared sensor MLX90614, capable of measuring the surface temperature of the human body or other objects. Unlike most contact‑type sensors, this sensor detects temperature by measuring infrared light emitted from distant objects, without physical contact. This gives it a wider temperature measurement range: ‑70 °C to + 380 °C. With a field of view of 90°, it can quickly and conveniently measure the… (M5Stack U028)
