There is much more serious news with regards to typhoons. This isn’t to belittle the importance of actual news, obviously. Ugh…Typhoons. In 2018 my wireless ipcam died. It was replaced by a whole NVR system for the outdoors. (Which has been a non iot post in draft mode for a year now) Countless dht22s and now the latest victim, my new BME280 which was outside … Continue reading Super Typhoon 11 (2019) AKA “Krosa” claims another sensor.
Last year I’ve had to replace the DHT-22 outdoor sensor several times during the peak and constant high humidity levels and the rainy season. I had discovered the BME280 sensor and read many good reviews. Wemos D1 Mini and BME280 Temperature, Humidity and Pressure Sensor Compare different i2c temperature and humidity sensors (SHT2x, SHT3x, SHT85, ..) Mentioned previously part1 part2 part3 I recently converted my … Continue reading Wayyyy too hot and humid but the BME280 troops on.
Part 1 / Part 2 Finally the AHT10 and BME280 sensors have arrived. First step soldering pins. Got to unwrap my newest soldering iron. Then loading up tasmota on the nodemcu.

Part 1 As I await my replacements parts I figured I’d try a few ideas to attempt a recovery of the defective DHT22. The first thing I decided to do was to remove the DHT22 from its partial enclosure. (Sensor part was exposed) Reconnected the sensor node and …. it’s still stuck at 99% humidity. I blew on it and the temperature changed but not … Continue reading DHT22 tinkering.
For over a year I would replace the DHT22 (or its small brother the DHT11) outdoors after a few months if I cared to do so. It’s located in a cutout of a small Tupperware container strapped under my deck roof. No rain can get to it but the roof is no completely opaque and lets a fair amount of sun through. Although the temperature … Continue reading DHT22 is useless outdoors: replacement.
It’s always a mystery what will arrive in the mail. Sometimes the delivery takes forever other times it’s here super fast. The items arrived 9 days from the purchase with free delivery. These items from different sellers must have be packed in a container that was almost full and ready to go or something. In any case I’m happy as the jump wire I wasn’t … Continue reading Colourful deliveries
Sunshine… I thought that this movement false positive was only a cheap ip camera thing. Alas no… Come to think of it two sensors are starting to act up. Upstairs bedroom and outside. The bedroom sensor used to give me false positives due to a bad power supply. The outdoor one now seems to alert a lot as the shadow of the house grows and … Continue reading RCWL-0516: More outdoor issues with the PIR AM312
