I recently stumbled over the Sensirion SHT31 Smart Gadget while reading the newest mycodo changelogs which supports it from version 7.0 on.

It has bluetooth connectivity and runs on a small battery. Checked the price and it's under 20eur shipped so i ordered some for me and a friend and also found that there are already designs for an enclosure for 3d printers. Send them to a friend who printed them for me and put everything together. There's an iOS and Android app for it (MyAmbience) to start, but i want to finally install mycodo and use it to log it (and get VPD logging too). It's unbelievable sensitive and the 4 of them we had in front of us showed nearly the identical value, so i think it's quite accurate too. So far it lives in its enclosure and does what it should (don't bother the not so nice enclosure):

So far i think it's quite a cheaper alternative to expensive products like the Pulse (minus the light logging) with lots of additional value when used with mycodo. Get your own :)

Mycodo is an automated monitoring and regulation system that was built to run on the Raspberry Pi (versions Zero, 1, 2, and 3).

Originally designed to cultivate edible mushrooms, Mycodo has grown to include the ability to do much more, including cultivating plants, culturing microorganisms, maintaining honey bee apiary homeostasis, incubating animals and eggs, maintaining aquatic systems, aging cheeses, fermenting foods and tobacco, cooking food (sous-vide), and more.

The system comprises a backend (daemon) and a frontend (user interface). The backend conducts measurements from sensors and devices, then coordinate a diverse set of responses to those measurements, including the ability to modulate outputs (relays, PWM, wireless outlets), regulate environmental conditions with electrical devices under PID control (steady regulation or changing over time), schedule timers, capture photos and stream video, trigger actions when measurements meet certain conditions (modulate relays, execute commands, notify by email, etc.), and more. The frontend is a web interface that enables easy navigation and configuration from any browser-enabled device.
