Condensation and damp are your biggest enemy. Cold nights, temperature swings and stagnant air create the perfect conditions for mould, bad smells, rot and expensive interior damage — all while your vehicle is sitting unattended for months.AirMix helps with that.Leave it inside your habitation area over winter and it silently monitors temperature and humidity, calculates the dew point, and automatically runs opposing fans to circulate air before condensation can form. Completely battery backed — no mains, no vehicle power, no hookup needed. Just switch it on, close the door, and leave it to do its job all winter long.No app. No Bluetooth. No setup. Switch it on and walk away.What AirMix does:<ul><li>Monitors temperature and humidity continuously using a precision SHT40 sensor</li><li>Calculates dew point — the real indicator of condensation risk, not just humidity alone</li><li>Pre-sniff pulse — runs fans briefly before each sample to flush stagnant air from the AirMix chimney and get a true reading</li><li>Automatically runs opposing fans when condensation risk is detected — one draws air in, one pushes air out</li><li>Adaptive monitoring — increases check frequency to every 5 minutes after a dew event until conditions are safe</li><li>Seasonal activation latch — LED shows 2 flashes after a dew event so you know it has been working during storage</li><li>Battery backed — runs completely independently from a quality RS Pro 18650 lithium-ion cell</li><li>USB-C charging — charge before you store, lasts the winter</li><li>LED guide printed on the enclosure — 1 flash = ready, 2 flashes = activated, 3 flashes = charge soon</li><li>Boot self-test fan dance — confirms both fans working at startup</li><li>Standard camera tripod mount — brass insert fitted, position it anywhere in your habitation area</li><li>PCB protected with MG Chemicals 419D acrylic conformal coating — moisture and vibration resistant</li></ul>Freestanding or tripod mounted — goes anywhere:AirMix sits flat on any surface or mounts directly onto a standard camera tripod using the brass insert fitted to the base. Position it exactly where condensation is a problem — under a bed, on a worktop, in a wardrobe space. No drilling, no permanent installation, completely repositionable season to season.Before you store for winter:<ul><li>Charge AirMix fully via USB-C</li><li>Switch on and confirm 1 flash heartbeat — ready</li><li>Place in your habitation area</li><li>Close up your motorhome or caravan and leave </li></ul>When you return in spring — 2 flashes on the LED tells you AirMix has been working. Your van is protected.What's in the box:<ul><li>AirMix unit in carbon fibre PLA enclosure</li><li>RS Pro 18650 lithium-ion cell installed — PCB protected, overcharge and over-discharge protected, UN and RoHS certified, original manufacturer's packaging included</li><li>Quick Start Guide</li></ul>Technical:<ul><li>Supply: RS Pro 18650 Li-ion cell, 3.7V 2600mAh, USB-C charging</li><li>Fans: dual opposing 5V PWM, variable speed</li><li>Sensor: SHT40 precision temperature and humidity</li><li>Dew point algorithm: August-Roche-Magnus</li><li>Activation threshold: RH ≥ 70% or dew point margin ≤ 2.5°C</li><li>Fan run: full power 60 seconds, cruise 70% for 5 minutes</li><li>Check interval: 15 minutes normal, 5 minutes after dew event</li><li>LED: 1 flash = ready, 2 = activated, 3 = low battery, 6 = sensor fault</li><li>Tripod mount: standard ¼" camera fitting via brass insert</li><li>Handbuilt and tested in the UK by Digconn Systems </li></ul> For full photo gallery including PCB detail and complete kit contents: <a href="https://drive.google.com/file/d/1B0C9SGAmy7WFY03bxpQSTucfockYEEMt/view?usp=sharing" rel="noopener noreferrer" target="_blank">[Click here to view]</a> 129.99 GBP https://digconn-shop.bigcartel.com/product/airmix-winter-storage-condensation-guardian https://assets.bigcartel.com/product_images/424461042/Pic1_1.png 119232531 new in stock 119218530 FridgeAir — Smart Fridge Fan Controller PRODUCT DESCRIPTION: Does your motorhome, caravan or campervan fridge struggle in hot weather? Compressor fridges work hard in summer — and without proper airflow the compressor overheats, efficiency drops, and lifespan shortens.FridgeAir fixes that.It monitors the temperature inside the compressor cavity and chimney behind your fridge using precision digital sensors and automatically runs cooling fans when they're needed — at exactly the right speed. Quiet when cool, powerful when hot. You'll never think about it again. No app. No Bluetooth. No setup. Just plug it in and it works.What FridgeAir does:<ul><li>Monitors top and bottom fridge compartment temperatures continuously</li><li>Runs fans automatically when the compressor area gets hot</li><li>Variable fan speed — ramps up with temperature, whisper quiet when cool</li><li>Protects your leisure battery — fans cut automatically if voltage drops too low, restart when charging resumes</li><li>Single sensor mode — works perfectly with just one sensor if your installation makes routing two sensors difficult</li><li>Green LED heartbeat confirms the unit is alive and working</li><li>Double flash warning when battery voltage is marginal — charge soon</li><li>Boot self-test — both fans run briefly at startup to confirm everything is working</li><li>Protects PCB with MG Chemicals 419D acrylic conformal coating for moisture and vibration resistance. </li></ul>Colour coded and clearly labelled — wiring takes minutes: A — 12V DC power input B — Top sensor (RED heat shrink) C — Bottom sensor (BLUE heat shrink) D — Top fan output E — Bottom fan output What's in the box:Controller only option:<ul><li>FridgeAir controller in carbon fibre PLA enclosure</li><li>2 x DS18B20 temperature sensors (red = top, blue = bottom)</li><li>2 x sensor mounting clip</li><li>2 x cable ties</li><li>Quick Start Guide</li></ul>Complete kit adds:<ul><li>2 x 12V DC 120x120mm fans with mounting hardware</li></ul>Technical: <ul><li> Supply: 12V DC (leisure battery)</li><li> Fan output: 12V PWM, dual channel, variable speed</li><li> Top fan triggers above 45°C, full speed at 65°C</li><li> Bottom fan triggers above 40°C</li><li> Smart delta-latch — automatically runs bottom fan when top is significantly hotter, ensuring cold air circulation even before bottom temperature rises</li><li> Battery warning below 12.3V, protection cuts in below 12.0V sustained, auto-recovers above 12.4V</li><li> Handbuilt and tested in the UK by Digconn Systems</li></ul> For full photo gallery including PCB detail and complete kit contents: <a href="https://drive.google.com/file/d/1-b1LKeH3KYq7pf97WTJ-36oTskwo_gEI/view?usp=sharing" rel="noopener noreferrer" target="_blank">[Click here to view]</a> 64.95 GBP https://digconn-shop.bigcartel.com/product/fridgeair-smart-fridge-fan-controller https://assets.bigcartel.com/product_images/424461024/Pic2_2.jpg 119218530 new in stock
