OpenMQTTGateway sensor box + IR blaster

thingiverse

Code from https://github.com/1technophile/OpenMQTTGateway is utilized on a wemos D1 mini, TSL2561, BME280 and HC-SR501 on a compact 170 Tie-points 35x47x8.5mm breadboard. For infrared operation, TSAL6200, TSOP38238, and 2N2222A components are used with 36ohm 1/4W resistors for VCC (capable of handling approximately 400mW but suitable for short bursts) and 330ohm for D0 connections. A 30-degree stand allows the infrared sensor to match a majority of opposing devices when placed on a desk. Required components include: - wemos D1 mini - TSL2561 (i2c) - BME280 (i2c) - HC-SR501 - 170 Tie-points breadboard - TSAL6200 - TSOP38238 - 2N2222A - 36 ohm resistor - 330 ohm resistor - m2 screws and nuts for mounting sensors (glue can be used as an alternative) Sample schematics are available, including Sparkfun's BME280 template, but only four pins will be utilized for i2c connections. Refer to the provided photo. The PIR sensor can be powered via a spare set of bridged 5v and Gnd connections. Potential future improvements include: - Adding reset button access - Integrating RF capabilities - Developing an external adaptor for 360-degree infrared operation with wires through the current IR led hole A photograph illustrating the setup is provided at https://i.imgur.com/zdbTH9A.png.
