Massachusetts-based Deimos Controls is getting ready to launch a crowdfunding marketing campaign for an open-hardware Ethernet-connected information acquisition module designed for tasks the place precision and accuracy are paramount: the Deimos DAQ.
“Deimos DAQ is a ready-to-use Ethernet information acquisition (DAQ) module with built-in precision voltage reference, precision clock, precision analog frontends, and PWM [Pulse-Width Modulation] outputs. No configuration or further modules are required,” Deimos Controls’ James Logan claims, “simply plug in energy and LAN, and it’s able to measure. In comparison with different DAQ gadgets, you may count on Deimos to ship distinctive information accuracy and timing in an attainable bundle. Everybody from researchers performing experiments at universities to hobbyists performing high-level science of their garages will love the ability Deimos offers them.”

The module itself is constructed round an STMicroelectronic STM32H7, on a board bristling with inputs and outputs: there is a pair of Okay-type thermocouple inputs with an anticipated 70K-1600 Kelvin temperature vary, 0.5K accuracy at room temperature and a 0.03K decision plus cold-junction compensation, matched-material connectors for 3 three-wire resistances, 4 4–20mA with an “precise full vary” of round 0-33mA at a 0.8µA decision, and 6 uncooked voltage inputs break up into two with 0.2× achieve, two with 1× achieve, one with a 25.7× achieve, and one with a 660× achieve, plus two frequency inputs , one counter enter, and one encoder enter. IF that is not sufficient, there are 4 16-bit PWM outputs and two 12-bit digital to analog converter (DAC) outputs.
Logan positions the gadget as being for the place precision is required however business gadgets thought of unaffordable — suggesting use-cases together with thermal-fluid and cryogenic programs, pressure measurement in structural testing, and ground-based testing of hydraulics, propellers and motors. The marketing campaign web page contains two schematics demonstrating methods to embody the Deimos DAQ in a undertaking: one exhibiting a single unit measuring and controlling a motor management check meeting, the opposite utilizing two items for simultaneous distant monitoring and actuation for turbine engine testing.
Design recordsdata and supply code for the undertaking have been revealed on GitHub below the person’s alternative of permissive Apache License 2 or MIT license; the crowdfunding marketing campaign is up on Crowd Provide for pre-registration, for individuals who want to be notified when funding opens.
