OpenMQTTGateway sensor box + IR blaster by w4rr3n

Last crawled date: 4 years, 2 months ago

Code from https://github.com/1technophile/OpenMQTTGateway
uses wemos D1 mini, TSL2561, BME280 and HC-SR501 on 170 Tie-points 35x47x8.5mm breadboard.
for IR I used TSAL6200, TSOP38238 and 2N2222A. 36ohm 1/4W resistor for VCC(resistor is subjected to about 400mW but 1/4W resistor should be fine for short bursts) and 330ohm for D0.
30deg stand allows IR to match majority of opposing devices when it is placed on desk.
BOM:
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 to mount sensors (glue is fine too)
Sample schematics:
only available template was sparkfun's bme280 but we will be only using 4 pins for i2c, refer to photo
PIR sensor can be powered through the spare set of bridged 5v and Gnd

Possible future improvement:
Reset button access
RF integration
Additional external adaptor for 360 degree IR (wires through current IR led hole)
