Weather station

 I have a Raspberry pi that collects data from my weather station and transmits the data to Home Assistant and also to the Codgers website.

Data includes atmospheric pressure, temperature, humidity and rainfall.  Pressure is measured using a BMP280, the next two variables use a DHT20, and rainfall is collected with a tipping bucket and recorded every 5 minutes.

The instruments are housed in a home-made Stevenson screen.

In February 2024, I added a DS18B20 temperature sensor, which is waterproof.  This is a "1-wire" connection to the pi and needs a resistor in the circuit (4.7K but I used 10K).

I buried the sensor at 10cm depth under the lawn to record soil temperature.

In December 2024, the top blew off in a storm and data went a bit haywire so there is a two day gap in data.

Vehicle tracker and boat sensor display (Project Samosa)

Image
Project Samosa The yacht club (APSC) bought a Jeanneau 36i in November 2024 and we thought we could add a few extra sensors and display data on an app using a tablet. MIT App Inventor is quite easy to use and free.  I have bought an ESP32 that gathers the data from the sensors and sends it to a pi Compute 4 (Sail Assist) that also sends boat data to the tablet. More later... Vehicle tracker (not used any more) My "van pi" (thanks Sue H) has various sensors attached. I have an independent leisure battery.  I have to charge this separately, as and when, at the moment.   Battery monitoring: I have an INA219 battery sensor that shows voltage, and current / power being used. I have a DHT20 sensor that measures temperature and humidity in the van (but in a cupboard where the sensor is located). A python program I called vansensors.py collects the data and sends it via MQTT to HA. I have a USB gps unit that lets the pi know where it is.  I have a program, gpsdatatest....

Doorbell notification to phone

 Doorbells are useful in that they let you know when someone wants to come into your house or deliver a parcel.  But what if you are in the garden or away from home?  You can buy expensive doorbells with video and the ability to let you talk to the person at the door via your mobile phone or you can try to do something simpler on the cheap. We had a bell push button linked to a 6 volt battery operated ding-dong chime.  I added a wire from the push button circuit, reduced the voltage to 3 volts, and connected this to a GPIO pin in the Raspberry pi model 4.  It could then sense when the voltage went on/off on a bell button push and, in theory, send a notification to my mobile phone.  It sort of worked but the notifications seldom came through so I guess I had something wrong in the code. We were struggling to hear the ding-dong chime, partly due to increasing age and partly due to the cheap bell push button, which people never seemed to press in the middle so...
