The hardware was assembled by connecting the Arduino UNO R4 WiFi, the PZEM 004T, the current transformer, and the OLED ...

There are plenty of drones (and other gadgets) you can buy online that use proprietary control protocols. Of course, reverse-engineering one of these protocols is a hacker community classic. Today, ...

For lab researchers and systems integrators/OEMs, the SmartTrak 50 is a true digital MFC and shares the same accuracy and repeatability as the flagship SmartTrak 100 with a few less features, slightly ...

Abstract: We present an optical flow meter based on a fiber ring resonator. The sensor utilizes flow-induced bending loss in the fiber ring resonator for fluid velocity sensing. A tapered segment of ...

Abstract: Transit-time flow meters need to compensate for cross-sensitivity to temperature. We show that Lamb wave-based setups are less affected by temperature. An optimality criterion is derived ...

lv_meter_indicator_t * indic1 = lv_meter_add_arc(meter, scale, indic_w, lv_palette_main(LV_PALETTE_ORANGE), 0); lv_meter_set_indicator_start_value(meter, indic1, 0 ...
