Smart water for Thai rice farmers
We build low-cost paddy water sensors, solar-powered pumps and a Thai-speaking AI assistant, so smallholder families in Isan can practise IRRI’s Alternate Wetting and Drying method and replace diesel pumping with solar.
Sense. Advise. Act.
Sense
LoRaWAN sensors in the paddy report the water level automatically — no daily walk to check each field.
The sensor →Advise
NaLog Agent answers in Thai or English, remembers each farmer’s paddies across sessions, and recommends when to irrigate.
The AI assistant →Act
A solar-powered pump replaces diesel. It switches remotely — and only after the farmer approves.
The solar pump →IRRI recommends Alternate Wetting and Drying (AWD). Research finds AWD can reduce water use by about23% without average yield loss, and roughly halve methane emissions from irrigated rice. We build the system that makes this practicable on Thai rice fields.
One loop, from paddy to pump
A sensor in an IRRI field tube reports the water level. Our NaLog platform tracks where each paddy is in the AWD cycle. NaLog Agent turns that into advice in Thai. When the field needs water, the farmer approves, and the solar pump re-floods the paddy.
The integration, and the commitment that a farmer approves every pump action, is what’s new.

My wife’s family grows rice across several paddies in Yasothon. Watching them walk to the fields every day to check the water, and pay for diesel to pump it, is why KhawTECH exists. We start with our own family’s fields, then the neighbours.
