SensorNodeESP

Data from sensor (PIR, CO2, smoke/water detectors...) is logged and sometimes sent to user (WhatsApp message, E-mail).

Server (Hub): ESP32 w/ buzzer

Web app - interface

Windows desktop app: backup logs (data from sensors)

Air Quality Data

ESP wakes up every 10 minutes and sends data from sensors to the hub (server) via ESP-NOW.

SCD30 - CO2

ENS160, DHT22 - air quality data (temp, hum, TVOC)

Client: ESP32, Li-Ion 18650 battery, ESP-NOW

ESP32 device wakes on a pin event (e.g. wires are submerged, PIR signals HIGH...), sends an ESP-NOW message to a predefined MAC address (hub) and then goes back to deep sleep.

Water detection

TODO

• Adjust WinBackupApp so it can run @Vranic
• Pay subscription to the CallMeBot: https://www.callmebot.com/support_callmebot/?phone=351919370635
• Hub:
  • Make 2nd version of Hub project - Hub /wo internet for places without internet access or with unknown net credentials. Communication with clients is done via ESP-NOW or radio (HC-12, LoRa, http...). Maybe it could have its own wireless network for web app access?
  • Web App:
    • Improve interface (chart.js disappears, shrinks)
  • Messages to the hub: ESP32CAM - take a picture, indoor vehicle - start, move...
    • Send message from Azure to the hub
    • Send message from web app or ESP device to the hub
    • (WIP) Make ESP32-C3 client that sleeps and gets a message from the hub
    • Why doesn't ESP32-C3 XIAO work with PIR sensor
    • Test current hub code @BanovoBrdo
    • Put Azure code in a class (e.g. AzureMessages)
    • ESP32-C3 turn up ESP32CAM and forward message from the hub
• Clients:
  • ClientLogger
    • Use it in SCD30 and ENS&DHT projects
  • (WIP) Put retrying logic in a class: Retryer
  • TimeSlotSend
    • Change getDeepSleepTime() so that it takes into account wake time and time spent in sending data
  • (OPT) Put TSS, LoggerMin and retrying logic in a class that will be used by most clients that report data regularly to the hub
  • (WIP) SCD30:
    • Button click: print log on Serial and send data (prev data or wait for new?) to the hub
  • esp32-wake-on-pin
  • Add more sensor nodes
    • Microphone (noise levels)

Add new client routine

• my_esp_now.h:
  • setPeers(): add new setPeer() call
    • setPeer(): set parameters: mac address, sensor type, device
  • Increase length of peers array: peer_info peers[]
  • OnDataRecv(): if (p->type == SensorType::...)
• lib/Common/src/ToString.cpp:
  • Add new members to arrays: StrSensorTypes[], SensorTypesComment[]
• Enums.h: Add new members to SensorType, Device
• index.html:
  • CmbChartParamsChange(): adjusting chart for sensors with temp and hum
  • lastChartParam: add default property for new sensor
