How to connect TP4056 battery management system with ESP8266
-
I wanted to run my NodeMCU board with a li-ion battery. How to use TP4056 safely with NodeMCU and monitor the battery status.
I am trying to build a pulse oximeter NodeMCU and Max30100 sensor.

Hi @Anish_Pillai , Are you using the TP4056 standalone module or specific breakout/ready-made boards with NodeMCU?
You can refer to the circuit below if you use generic readymade modules.

Hi @binishmatheww , Welcome to Makergram.
I see you want to build a GPS Logger. For that, you can use any basic GPS module available in the market such as NEO-6M GPS Module or any from the list here.
After that, you need to choose a microcontroller, which can communicate with the GPS module read the GPS and translate the NMEA (data format for GPS packets) to a more usable format (you can do the post-processing in the phone too).
Then you can send the data to hone via BLE, for this you can use a BLE-supported microcontroller or use a standalone BLE co-processor. My suggestion is to go with esp32 as it has BLE support and other cores can be used for the GPS data acquisition. To do the post-processing and other things you can do with the mobile app.
You can split the project into different parts.
GPS Data Acquisition. (You can use Arduino IDE + ESP32/Pico W + GPS module of your choice) GPS data translation (There will be Arduino lib which can make the translation easier) Send Data to the mobile app via BLE (Arduino IDE + ESP32/Pico W + BLE LIB + Mobile application).Hope you get an idea, please check and let us know. Happy building.

I want to build a device which collects location information with GPS using the internet via a SIM card.
I also need this data to be transferred to my Android device via a USB cable for realtime processing.Currently, in one of my Android apps, I collect location information from the built-in GPS module of the mobile phone. But this is sometimes inaccurate due to hardware limitations and Operating system throttling.
This affects real-time processing in the app.So, I want to make a dedicated GPS device which outputs the location data via a USB cable to the mobile phone so that the app could process it in real-time.

Hi,
I am looking into developing a GPS module which communicates with an Android phone via a USB cable.
I am an Android engineer who is new to hardware engineering.Any help is much appreciated.

@sarathslab why your are choosing this perticular LoRa module, can you please elaborate your use case. Personally I don't have experience with this module. When i go through the details of this hardware find like this is a UART device and so you can communicate by using the AT comments. And this will be available on the datasheet I guess. Also if you don't want to use this perticular module I suggest sx1276 or LoRa E5 from Seeedstudio. And by using this you can able to connect with helium network or things network. If you want to know more about this I think Salman can help.
