OP.90 and OP.180 are two limit switches with different orientation placements. Built based on the ITR9606, which consists of an infrared emitting diode and a silicon phototransistor.
They are used for controlling machinery as part of a control system, as a safety interlock, or to count objects passing a point. A limit switch is an electromechanical device that consists of an actuator mechanically linked to a set of contacts. When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection

The MR24BSD1 24GHz radar module applies Doppler radar detection technology to implement human sleep quality monitoring, detecting body moving and stationary along with human breathing rate, providing a fully private and secure environment, independently from other noisy influences. It represents useful privacy-protected, secure sensor radar systems in smart home applications like sleep safety alarm, sleep respiratory detection, movement monitoring.

Compared to the traditional PIR sensor, 24GHz mmWave sensors offer the better performance of human activities detection for high sensitivity. The transmitting mmWave is millimeter-level which means mmWave sensors will maintain sensing status even if there is a shelter block the detected object. Unlike rapid responding to PIR sensor, mmWave sensors detect objects continuously. All of which makes mmWave sensors quite useful in the living rooms, hotels, or even prison that requires monitoring all the time.

The MR24BSD1 radar leverages the superior performance of 24GHz mmWave to monitor human sleep quality implements based on received breathing rate and body movement while people falling asleep. Furthermore, the radar is independent of temperature, humidity, noise, airflow, dust, light, and other environmental influences. Designed as low power output, the radar maintains health-friendly working status while it is detected. For privacy protection, the radar uses the properties of millimeter waves that only process wave signals to provide a fully private sensing environment.

The radar supports secondary development and it adapts to various scenarios applications as it includes scene recognition capability that identifies occupied/unoccupied and personnel activity status. The detected area is a Horizontal 40°/vertical 40° sector beam and it maximum detect 1.5 meters of body movement and 1.5 meters human breathing rate.

This microwave sensor is a microwave module that can transmit an electromagnetic wave of 5.8GHz. It can detect the difference between the transmitted wave and the reflection wave to identify whether there is an object moving in the detection area.

Different from the traditional sensors that can only detect human presence by detecting big body movements, this microwave sensor can perform well in detecting small movements like breathing so as to determine human presence even if the person is sitting or sleeping. The detected result can be output through the serial port or high/low level of the I/O port. Featuring high reliability and sensitivity, and strong anti-interference, it is small and easy to integrate, which can be widely used in fields that require motion detection, such as lighting, security, home, home appliances, hotels, garages, buildings, traffic, etc.
