In example implementations, a door monitoring sensor is provided. The door monitoring sensor includes a communication interface to transmit an alarm when a door operates outside of operational parameters of the door, an angular sensor to measure rotational movement of the a door, a movement sensor to detect movement along an x-y-z coordinate plane, a radar sensor to detect an object, a rechargeable power supply to provide power to the angular sensor, the movement sensor, and the radar sensor, and a processor. The processor is communicatively coupled to the communication interface, the angular sensor, the movement sensor, and the radar sensor. The processor is to determine that the door is moving outside of the operational parameters of the door and generate the alarm that is transmitted by the communication interface in response to determination that the door is moving outside of the operational parameters of the door.
