Hello all. I am writing this topic in case someone wants to help me find out how we can use Channel B of the HX711 amplifier to measure some battery . Because i am very new to Arduino and i am coming from programming and not electronics (that as you can see from my signature i hardly know what is a transistor :o 😕 ) i am putting here my results …
However, the algorithm did not work correctly when the converter started, which creates a limitation in a battery system with many converters. A detection method for high-impedance DC arcs using Hurst exponents with a two-stage filtering is proposed, which achieves a detection time of 50–100 ms [55]. This detection method has only a small ...
Because the TLV185x/6x devices are fail-safe, the devices can handle voltage spikes independent of the supply, up to 40 V. The internal reverse battery protection also means that the TLV185x/6x is directly connected to the battery and if the polarity of the battery voltages changes for any reason, the input pins of the comparator remain undamaged.

First make sure you are running the latest version of Zigbee2MQTT; Stop Zigbee2MQTT; Determine whether migrating requires re-pairing of your devices. If re-pairing is required: remove data/coordinator_backup.json (if it exists) and data/database.db; If re-pairing is not required: copy the ieee address of the old adapter into the new one; Update the serial-> …
The resistor connected to the PROG pin sets the charge current to 1000 / R Amps, if I''ve read the datasheet right. Usually I either use 2KOhm for 500mA, or 10KOhm for 100mA if I have a small battery. A good rule of thumb is to charge at a maximum of one Coulomb, and a quick shortcut for that is to estimate that you can charge an XmAh …
