LED System vs OBD2 Scanner + Engine Sound

这是一个用来管理LED价格牌的APP，用户通过这个应用可以集中管理分布于各地的价格牌。价格牌被分组管理。用户可以查询和设置价格牌的显示数值，也可以查询和设置价格牌的亮度。每个价格牌最多可显示12行价格信息，每行可轮流显示现金价格和信用卡价格。 用户需要有权限才能操作，用户操作权限分为4级： 1. 超级管理员：整个系统的最高管理者，管理超级操作员和一般管理员。 2. 超级操作员：由超级管用员创建，可以查看系统中所有的价格牌信息，但是没有设置权限。 3. 一般管理员：由超级管用员创建，可以增删分组，增删价格牌，增删一般操作员，给一般操作员分配对分组的权限。 4. 一般操作员：由一般管理员创建，具体权限由创建他的一般管理员分配，可以拥有对分组的如下权限：查看分组价格牌、编辑分组价格牌、设置分组价格牌显示的价格、升级价格牌固件。

See — and hear — your car in real time. Connect an ELM327 Bluetooth (BLE) adapter and the app turns live OBD2 data into a fast, modern dashboard: RPM, speed, coolant, throttle, fuel, and every sensor your vehicle supports, auto-detected. No subscription. Ever. WHAT MAKES IT DIFFERENT • A genuinely modern interface — not the dated look of most OBD apps • A one-of-a-kind engine-sound simulation driven by your real RPM • Speed and RPM drawn on the map, color-coded (satellite view included) • Buy once for Pro — no monthly fees, unlike many scanners BUILD YOUR OWN DASHBOARD Mix and match four widget types — digital tiles, analog needle gauges, live charts, and the trip map — then reorder them into your own instrument screen. A mirrored HUD mode projects your speed onto the windshield at night. FIVE FOCUSED TABS • Dashboard — your own widget layout, plus HUD mode • Data — every live sensor, overlaid or separate charts, CSV export (long or spreadsheet-friendly wide format) • Drive — trip computer with fuel economy, the color-coded track map, a G-force ball, and 0–100 timing • Engine Sound — procedural sound that follows your real RPM (all presets free) • Tools — adapter info and communication log FREE INCLUDES Live data, the dashboard, track map, trip computer, HUD, and engine sound — free, with a small banner ad. PRO (ONE-TIME PURCHASE, OPTIONAL) • Unlimited CSV logging • Save your 0–100 and G-force runs • Remove ads Prefer just no ads? A cheaper ad-removal-only purchase is also available. NO ACCOUNT NEEDED Your vehicle data comes straight from the ELM327 adapter over Bluetooth and is processed on your device — there is no developer server collecting it. The free version shows ads served by Google's ad SDK (buy Ad Removal or Pro and no ads are shown). Try it with no hardware using the built-in demo mode. REQUIRES an ELM327-compatible Bluetooth LE (BLE) OBD2 adapter and a vehicle with an OBD2 port (most cars sold since 2008). SUPPORT Questions or ideas? Contact: support@takasawadynamics.com
