The SPECULOOS project is dedicated to the discovery of transiting exoplanets around ultracool dwarfs through high-precision ground-based observations across visible and infrared wavelengths. To enhance sensitivity to these cool stars, we have implemented SPIRIT, a novel infrared detector utilising CMOS technology instead of traditional CCDs. In this talk, I will present my work optimising SPIRIT’s performance for detecting exoplanet transits and share our results after the first months of observations. I will discuss the prospects for using CMOS detectors for exoplanet research, their potential for detecting rocky planets around ultracool dwarfs, and how this technology represents a promising advancement for ground-based observations in the NIR. I will also highlight early discoveries made with SPIRIT, including the warm Neptune TOI-2407b.
