bbokser/persuasive_waker
An open source hardware alarm clock that can't be snoozed or turned off.
Boards in 4 GitHub repositories, designed in KiCad, that use the SHT40-BD1B-R2 by Sensirion (-40℃~+125℃ 0%RH~100%RH 1.08V~3.6V 16bit 400nA Factory calibration、Built-in heater I2C ±0.2℃ ±1.8%RH DFN-4(1.5x1.5) Temperature and Humidity Sensor ROHS). See how each wires it, with its parts, size, README and files; the SHT40-BD1B-R2’s symbol, footprint and pinout are on its own page.
