Hi,
I was about to write my own driver for an HC-SR04 sensor module when I came across yours 👍 )
My sensor is connected through level converters to GPIO4/5 on an ESP-07 module.
Seems to work just fine, distance is off (too short) by about 10mm when measured from the front of the sensor.
I've made a couple minor tweaks so the code builds on the more recent ESP SDKs (0.9.5 - 1.3.0)
Regards,
Marc
