Single photon detection modules have important applications in many fields. However, the existing single photon detection modules rely on imported chips. In this paper, a 1550 nm single photon detection module based on domestic components is developed. The trigger signal processing circuit is improved to avoid the use of imported chips. Under the action of trigger signal, the avalanche photodiode enters Geiger mode. When the avalanche photodiode in Geiger mode receives a photon, the avalanche signal is generated. In the output signal of the avalanche photodiode, the intensity of the avalanche signal is less than that of the noise signal. After eliminating noise and amplifying the output signal of the avalanche photodiode, the avalanche signal is identified by the comparator. In order to suppress the dark current and dark count of the avalanche diode, MCU and temperature control circuits are used to ensure that avalanche photodiode works in stable low temperature environment. The experimental results show that when the detection efficiency is 12%, the dark-count and after-pulse probability are 7.7×10^-6 gate^-1 and 2%, respectively. The parameters all meet the expected targets. The scheme has simple structure and realizes localization.
