Stabilised the TMP-36 sensors with a 0.1uF capacitor.

I tackled measurement instability on several fronts…

Oscillation – too frequent switching on and off of the heating circuit(s).

Two problems I encountered along the way were… The whole RasPiO duino temperature control system It Needs Smoothing and Anti-Oscillation And, because we all love LEDs, let’s have some of those too, as indicators. So, since I’ve got the RasPiO ® duino to play with, I thought I’d use that and a little relay board, some TMP-36 sensors and a 12V Halogen bulb or two.

Liz mentioned, on the Foundation’s blog last week, an SD card corrupting because someone removed the power lead. I haven’t had an SD card corruption for over a year, but I know other people have. You could use a Pi, but there is still a chance of SD card corruption, so it’s a bit less bullet-proof. That sounds like a job for a small, autonomous, low-power device that can read temperature sensors and switch relays.Īn arduino type device is ideal for this because, if there’s a power cut, it’ll ‘just work’ when the power is restored. What I need is a way of safely and gently heating the surrounding area, or the pipe itself, if/when the pipe temperature gets too low. I know there are ‘proper’ solutions for this, but where’s the fun in that? I want to make my own. That pipe and the inlet valve are what I want to protect. The central heating water is drained and the system is empty, but there’s a 3 foot pipe sticking up from the ground before it gets to the inlet valve. That’s bad because if the water in our inlet pipe freezes, it could burst. In a very harsh winter, the temperature in the basement, where the water inlet is, can get close to zero. I want a way of preventing the water inlet pipe freezing in the basement of our house in Poland. bob099 liked Dedicated Control Board for Mobile Robots with Whe.But the board is not really what today’s post is about.bob099 liked UBASIC And The Need For Speed.Aldwin has updated the project titled Compact LoRa Environmental Sensor.

When this material absorbs rain water, it begins to expand and triggers the switch. It’s a switch surrounded by a spongy material.

One interesting part is the commercial rain sensor. While the Yun has on-board WiFi, there is no possibility to attach an external antenna directly to the test SMA socket. This is handy since the Yun is mounted inside an enclosure where the signal strength is very weak. He’s also got another tutorial describing how to connect a USB WiFi adapter to the Yun. describes how to read three states of the switch (On-Off-On) when connected to a single analog input of the Arduino. These allow the outputs to be switched off or on manually, or controlled via the Yun when in auto mode. A switch panel has indicator Status LED’s and three position switches. The Arduino Yun activates solenoid valves via a relay shield.

The web interface is divided in to three tabs – “runtime” for manual control, “setup” to configure the scheduling, and “events” to view system logs.

The code is fully customizable and open source, with code available from github repository. It’s also possible to manually control the various water solenoids. This allows scheduling in a manner similar to creating appointments in Outlook. Irrighino is a complete watering system based on the Arduino Yun, featuring a user friendly AJAX interface. He used standard off the shelf, hardware to keep it simple. just created a new one by building the irrighino watering system. There are many different ways to keep your plants watered on a schedule.
