TSM323 is a serial sensor access controller (SSAC) module manufactured by Sensata Technologies. It is used to interface with a variety of sensors, such as flow and pressure, pressure, temperature, humidity, level, and speed sensors. It provides an efficient and reliable means of communicating with the sensors, allowing users to select the parameters required for each type of sensor and configure the module’s settings to suit each individual application. The module also incorporates a low-power feature which allows it to be operated on batteries in applications where there is no access to AC power. Additionally, the module offers a see-through connector for easy installation, and is resistant to electromagnetic interference for reliable operation.
