Controlled agriculture system

I made a project “controlled agriculture system” in which I have implemented proximity sensor(along with buzzer and led), LDR, soil moisture sensor, controlled irrigation system(using water pump) and LM35 sensor. Is there any way that i can control these sensors using my mobile phone(an app implementation)?
For example: If i want to reduce the temperature of the compound, I can install a fan which i can control with an app on my phone.
My question is how do i start doing this? Also one bolt module only allows for one sensor to work at a time (no concurrent control). How do I solve that problem?

You can use an Arduino along with your Bolt Module. And with the UART communication, you can get started and build a project with multiple sensors which require analog pins.

You can refer to Getting Started with Arduino with Bolt IoT workshop video for the same>

Documentation links - https://docs.boltiot.com/docs/arduino-library
GitHub - Inventrom/boltiot-arduino-helper

For making Apps without much coding, you can refer to https://bubble.io/ or https://appinventor.mit.edu/ and use the Bolt API to trigger or get data from the module.

Let me know if you have any other queries.
