After the batteries run out, the user can easily open the enclosure and replace them with 2 common AAA batteries. It will send periodically data every day as well as for each door open/close action. It also counts the door open times and calculates the last door open duration. The user can also disable the uplink for each open/close event, instead, the device can count each open event and uplink periodically. It also has the open alarm feature, the user can set this feature so the device will send an alarm if the door has been open for a certain time. Each LDS02 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to the LoRaWAN server and it will auto-connect after power on.

SparkFun SparkFun MicroMod DIY Carrier Kit (5 pack)
The MicroMod DIY Carrier Kit includes five M.2 connectors (4.2mm height), screws, and standoffs so that you can get all the special parts you may need to make your own carrier board. MicroMod uses the standard M.2 connector. This is the same connector found on modern motherboards and laptops. There are various locations for the plastic ‘key’ on the M.2 connector to prevent a user from inserting an incompatible device. The MicroMod standard uses the ‘E’ key and further modifies the M.2 standard by moving the mounting screw 4mm to the side. The ‘E’ key is fairly common so a user could insert an M.2 compatible Wifi module. Still, because the screw mount doesn’t align, the user would not secure an incompatible device into a MicroMod carrier board. Features 5x Machine Screws Phillips Head #0 (but #00 to #1 works) Thread: M2.5 Length: 3 mm 5x SMD Reflow Compatible Standoffs Thread: M2.5 x 0.4 Height: 2.5 mm 5x M.2 MicroMod Connectors Key: E Height: 4.2 mm Pin count: 67 Pitch: 0.5 mm

Raspberry Pi Foundation Raspberry Pi Global Shutter Camera
The Raspberry Pi Global Shutter Camera is a specialised 1.6 MP camera from Raspberry Pi that is able to capture rapid motion without introducing artefacts typical of rolling shutter cameras. It is ideally suited to fast motion photography and to machine vision applications, where even small amounts of distortion can seriously degrade inference performance. With a large pixel size of 3.45 x 3.45 μm providing high light sensitivity, the Global Shutter Camera can operate with short exposure times (as low as 30 μs with adequate lighting), an advantage for high-speed photography. It features a 1.6 MP Sony IMX296 sensor, and it has the same C/CS-mount lens assembly as the Raspberry Pi High Quality Camera, for compatibility with the same broad variety of lenses. In common with other global shutter sensors, the IMX296 has a lower resolution than similarly sized rolling shutter sensors; a low pixel count is appropriate for machine vision applications, where high-resolution images are challenging to process in real time. The Global Shutter Camera's lower resolution means that with appropriate lens magnification, an image suitable for processing by a machine vision model can be captured natively. The Raspberry Pi Global Shutter Camera is compatible with any Raspberry Pi computer that has a CSI connector. Specifications Form factor 38 x 38 x 19.8 mm (29.5 mm adapter and dust cap) Weight 34 g (41 g with adapter and dust cap) Sensor Sony IMX296LQR-C Resolution 1.58 MP (color) Sensor size 6.3 mm (sensor diagonal) Pixel size 3.45 x 3.45 μm Output RAW10 Back focus length of lens Adjustable (12.5-22.4 mm) Lens standards CS-MountC-Mount (C-CS adapter included) IR cut filter Integrated Ribbon cable length 150 mm Included accessories C-CS mount adapterScrewdriver Tripod mount 1/4”-20 Included Raspberry Pi Global Shutter Camera C-CS mount adapter Screwdriver Ribbon cable (150 mm) Downloads Datasheet

Arduino Arduino Pro Portenta H7
Portenta H7 follows the Arduino MKR form factor, but enhanced with the Portenta family 80-pin high-density connector. Program it with high-level languages and AI while performing low-latency operations on its customizable hardware. Portenta H7 simultaneously runs high level code along with real time tasks. The design includes two processors that can run tasks in parallel. For example, is possible to execute Arduino compiled code along with MicroPython one, and have both cores to communicate with one another. The Portenta functionality is two-fold, it can either be running like any other embedded microcontroller board, or as the main processor of an embedded computer. Portenta can easily run processes created with TensorFlow Lite, you could have one of the cores computing a computer vision algorithm on the fly, while the other could be making low-level operations like controlling a motor, or acting as a user interface. Use Portenta when performance is key, among other cases, we envision it to be part of: High-end industrial machinery Laboratory equipment Computer vision PLCs Industry-ready user interfaces Robotics controller Mission-critical devices Dedicated stationary computer High-speed booting computation (ms) Two Parallel Cores H7's main processor is the dual core STM32H747 including a Cortex M7 running at 480 MHz and a Cortex-M4 running at 240 MHz. The two cores communicate via a Remote Procedure Call mechanism that allows calling functions on the other processor seamlessly. Both processors share all the in-chip peripherals and can run: Arduino sketches on top of the ARM Mbed OS Native Mbed applications MicroPython / JavaScript via an interpreter TensorFlow Lite Graphics Accelerator Probably one of the most exciting features of the Portenta H7 is the possibility of connecting an external monitor to build your own dedicated embedded computer with a user interface. This is possible thanks to the STM32H747 processor's on-chip GPU, the Chrom-ART Accelerator. Besides the GPU, the chip includes a dedicated JPEG encoder and decoder. A new standard for pinouts The Portenta family adds two 80-pin high density connectors at the bottom of the board. This ensures scalability for a wide range of applications by simply upgrading your Portenta board to the one suiting your needs. On-board Connectivity The onboard wireless module allows to simultaneously manage WiFi and Bluetooth connectivity. The WiFi interface can be operated as an Access Point, as a Station or as a dual mode simultaneous AP/STA and can handle up to 65 Mbps transfer rate. Bluetooth interface supports Bluetooth Classic and Bluetooth Low Energy. It is also possible to expose a series of different wired interfaces like UART, SPI, or I²C, both through some of the MKR styled connectors, or through the new Arduino industrial 80-pin connector pair. The 80-pin connector pair provides additional features including Ethernet. USB-C Multipurpose Connector The board's programming connector is a USB-C port that can also be used to power the board, as a USB Hub, to connect a DisplayPort monitor, or to deliver power to OTG connected devices.
