Giveaway Week – ANAVI Gas Detector Starter Kit

ANAVI ESP8266 Gas Detector Display

Leon ANAVI makes from fun little boards for home automation, either ESP8266 based, or pHAT for Raspberry Pi boards. Earlier this year, I wrote about my experience getting ANAVI Gas Detector with Home Assistant. Now that’s I’m done, I’m giving away the starter kit that includes the ESP8266 board, an acrylic case, an OLED display, a USB to serial adapter, and MQ135 air quality sensor. The board is open-source hardware, meaning everything is open source from the KiCAD files to the Android sketch running on the board. It’s very easy to get started, as you can just connect a USB cable for power, and after configuring WiFi you can see the air quality  – either Poor, Moderate or Good – displayed on the OLED display, and you can easily see the data in a web dashboard after setting up Home Assistant. Everything shown in the top photo will be given away to one lucky winner. To enter the draw simply …

Dragino LHT65 is a $30 LoRaWAN Temperature & Humidity Sensor

LHT65 LoRaWAN Temperature & Humidity Sensor

If you’d like to monitor temperature and/or humidity in remote locations, one way is to get a LoRaWAN gateway, and setup a few LoRaWAN nodes connected to your own temperature & humidity sensors, and add a battery and enclosure. But if you’d like to save some time, and get a turnkey solution, Dragino LHT65 LoRaWAN temperature & humidity sensor may be an option. The sensor comes with an internal SHT20 sensor, and as well as an external DS18B20 waterproof temperature sensor.

Daytripper Uses Laser Time-of-Flight Sensor to Hide Your Slacking Off From Your Boss

Have you ever run into that awkward situation where you were actively busy doing something totally off company’s duties on the computer and got caught red-handed, or an unknown intruder ventured into your privacy, and you got in this awkward unexplained situation. If yes, then you are not alone. Work could be boring sometimes, and some of us do like to take some steam off probably by playing some video games, watch funny videos, or do something outside the blues. It is nice until a superior or a colleague catches us doing that.  One way to avoid this is by closely observing our surrounding while getting ourselves immersed but doesn’t always work well because it is super easy to slack off. Well, you don’t have to worry anymore thanks to an innovative project designed by dekuNukem called Daytripper. Daytripper is a laser tripwire that will help you automatically hide your active computer windows when an event occurs. Think about Daytripper …

PT100 Resistance Temperature Detector (RTD) Probes Support Extreme Temperature Ranges

WZP-187-PT100 Temperature Probe

I’ve been playing with temperature measurements in several hardware platforms such as Texas Instruments eZ430-Chronos Watch, Sonoff SC environmental monitor, Wemos D1 board with aDHT21 temperature sensor, or more recently ANAVI Thermometer with the last three platforms based on ESP8266 WiSoC. All four devices/boards above have temperature sensors designed to measure ambient temperature with for example DHT22 having a range of -40 to +125 degrees Celsius.  I had also come across DS18B20 waterproof temperature probe to measure liquid temperature several times with a range of  -55 to 125°C. Good for most use cases, and for example you could check boiling water with the later. But I had never really thought about measuring data for much lower or much higher temperatures, and this morning I came across two “PT100” temperature probes on IC Station new arrivals feed namely WZP-187 ($4.89) and an unnamed probe ($3.42) respectively capable of -200°C to +400°C and 0°C to 800°C ranges respectively. PT100 Temperature Probes Specifications …

Getting Started with Temperature & Humidity Sensors on ESP8266 using ANAVI Thermometer

ANAVI Thermometer Air / Humidity / Water

ANAVI Thermometer was launched on CrowdSupply in January.  It is an ESP8266 WiFi board with a built-in DHT22 temperature and humidity sensor, support for external DS18B20 waterproof temperature sensor, as well as other sensors thanks to three I2C sensors. I received the ANAVI Thermometer starter kit last month, and I’ve only found time to play with it in the last few days. I’ll start with a unboxing, assembly guide, before showing it action, and I’ll try to make it interface with Home Assistant over MQTT. ANAVI Thermometer Starter Kit Unboxing The kit comes with ANAVI Thermometer board, a plastic stand, a USB to TTL debug board, an I2C OLED display, a few nuts and bolts, and a couple of KiCad and ANAVI stickers. Leon ANAVI also added a traffic light board and LEDs, but it’s not normally part of the kit 🙂 ANAVI Thermometer board include an ESP8266 module, AM2302 (wired DHT 22) temperature and humidity sensor, a terminal block …
