Graphical display is also one of my requirements alongwith data. What level of data security exists in running dashboard data ? Can i keep privacy with the fetched data?

Hi all

I am quite new in this field so wanna know how would i start designing dashboard for household energy consumption and what kind of options i could have for beautifying the display ? I am getting the readings from an energy server (to be disclosed later) with a resolution(interval) of 10 minutes. From these readings i will categorize them into energy and water consumption columns. Currently it should only be accessed through the browser. (not thinking about app creation )

Please guide and assist

Thanks !

Hi,

So i just want to install water flow measuring sensors in my kitchen and washroom to measure the volume of water usage every month or fortnightly. I have a datalogger which takes input as modbus so sensors should work directly on modbus or interface may be used between sensor and data loggers.

Please give me some info regarding water flow sensors available in the markets which suits my demand (they should send the data not just those which displays the real time flow)

Thanks

Thanks for clarifying. System would generate approx 600 Volts and 8 Amps from PV. Hardly there would not be more than 15 I/O's . Which would be cheaper and reliable option for controller to use with esp8266 ? Are there any controllers specifically for data monitoring? lets say if i connect voltage and current sensors directly to that controller ? I know there are some DSP's in the market but they are too expensive. I have seen LV-25P and LA-P sensors for voltage and current sensing in another circuit however never interfaced by myself.

@gohan thanks..But please go a little slower (I know you are a pro but i am just thinking how this connection will work) You mean i could use ESP8266 with any controller (controller will read the data from sensors) and then controller will connect to ESP8266 for sending data over the internet. But for now i just want to measure the data and store it somewhere in any memory. Wifi and other stuff comes next i guess. Can you please draw me a rough diagram for explaining this connection?

@BartE I want to measure the PV module output which is going into the battery.. and output from battery to inverter.. There is only a meter connected at the load side after the inverter (AC) which gives load consumption data however i am blind at the input side (PV). By getting the data i would know many things happening at the input side (losses,efficiency,PV generation etc) currently there is nothing to communicate with PV and batteries.

Thanks gohan.

I want to store data in any kind of memory linked to my PC and later i could use it for calculation and my record purpose. Currently I dont want to use website or online portal for communication. I am kind of novice but have some knowledge in electronics field. System contains 8kWh battery. For test purpose i want to monitor and save the data.

Hi all,

I want to install a dc meter between my solar panel and battery for recording (logging) PV generated output from Solar panel. Also i am thinking to connect another meter after the battery to see outgoing power after the battery. My questions are:

1. Are there any feasible and cheap solutions to make certain circuit based on Voltage current hall sensors with MCU's to record PV generated data ? what could be the method to store analog data coming from sensors to store in some memory.

2. Any cheap product in the market for dc parameter measuring and data logging. (at least for 2 months).

Thank you. this is my first post here i will look forward for responses from you guys.

Cheers
