Pololu 9V, 2.3A Step-Down Voltage Regulator D24V22F9 Temp/Humidity Sensor any external power supply must

any external power supply must be connected to IN2

- Peak Efficiency Point: 20N @ 8mm/s

A full datasheet for the relays used on the ETH008 is here: HF115FD datasheet

The sensor operating mode is user-configurable and allows selecting between different ODRs (down to 1Hz) or the one-shot mode for battery saving

ESP32-S2-Saola-1 is equipped with ESP32-S2-WROOM module

Pololu 9V, 2.3A Step-Down Voltage Regulator D24V22F9 Temp/Humidity Sensor any external power supply mustThis small synchronous switching step down (or buck) regulator takes an input voltage of up to 36 V and efficiently reduces it to 9 V. The board measures only 0. 7 0. 7 yet delivers typical continuous output currents between 1. 5 A and 2. 3 A, depending on the input voltage, which makes this regulator well suited for powering moderate loads like sensors or small motors. An optional enable input can be used to put the regulator in a low power state
