Re: RPi Cam Web Interface

Hello, New to this forum and unsure if this is the right place to post my small issue. I have setup my cam and it was accessible until last night. However, this morning when I login all I can see is the "Index of /" folder and no cam in view. Could someone please explain how I can troubleshoot this...

Re: Wireless soil moisture sensor

Sounds good. Couple of last remarks before you get stuck in. Those modules have a 3.2:1 divider between the external pin and the ESP8266 ADC so you can connect moisture sensor output straight in. The moisture sensors like I use have a fairly high output impedance (~10K) so best read by something wit...

Re: Wireless soil moisture sensor

As I said the integrated module may suit you if you want to keep the hardware effort to a minimum. You would get a usable if not the best battery life and youjust recharge when they run low. Don't however believe the 9800mAH claim for a 18650 LIPO battery. That is is pure mythology. Look at the revi...

Re: Wireless soil moisture sensor

Those linked items are basically like the development boards I mentioned but with built in battery holder / charger. They are certainly fine for doing development but you won't get the ultimate battery life even when you put use sleep. They will typically draw 0.3 to 0.5mA in sleep due to the extra ...

Re: Wireless soil moisture sensor

Can you post links to the sensor you use and whatever boards you use for the battery powered solution? I didn't think of running 1 per pot, thought one controllong 8. Your way seems to make sense and be easier. Because it only sleeps for a little while, have you had the corrosion issues I've seen o...

Re: Wireless soil moisture sensor

Just answering a couple more of your questions. The moisture sensors I use can be powered from 3.3 - 5V. Internally they use a LDO regulator. They could just be connected to the 3.3V supply for the ESP module but they do draw about 5mA supply current which would drain a battery powered solution. Tha...

Re: Wireless soil moisture sensor

Yes, the ESP8266 has 1 ADC input (and about 9 digital GPIO). One could add on a I2C multichannel analog chip, but I wouldn't do it that way myself. The modules are so cheap (~UKP 1.50) that I would just use just 1 per sensor. They all communicate back to the central point over wifi. That way you avo...

Re: Wireless soil moisture sensor

Yes. Using esp8266 is a good solution here. It can also be made battery operated with very long battery life by using the deep sleep capability of the ESP8266 so that it wakes up at suitable intervals, takes a measurement and communicates it. I use it in a pot plant watering system. https://www.inst...

Re: Can I using wi-fi connect two pi's together without a hotspot?

You need one of the Pi's to be an access point (AP). This is like half of a hotspot.

See first part of https://www.raspberrypi.org/documentati ... s-point.md for a comprehensive tutorial.

Note that you could skip the dhcp part if you set up static ip addresses.

Re: Spoofing Mac Address on Stretch

Yes. That still works on stretch for the built in unit, but they have unique mac addresses so the need to spoof is less.

My use case was for external usb LAN adapters where the cmdline.txt method is not applicable.

I agree you want to look at the security implications more carefully, particularly for an item like a door opener. The reason why your sudoer method wouldn't work is because the /var/www/html/openDoor.py is not an executable command by itself. It has to be run by python. I suspect you are using sudo...
